Terms of Service

Effective date: 19th September 2026

1. About these Terms

These Terms govern your use of the Moulding Optimisation Ltd website, website account, downloads, software-related services, purchases and licence-management services.

Company: Moulding Optimisation Ltd
Company number: 09680478
VAT number: 217 3064 33
Registered office: C/O SG Accounting, 1 Cedar Office Park, Cobham Road, Wimborne, United Kingdom, BH21 7SB
Website: https://mouldingoptimisation.ltd
Contact: https://mouldingoptimisation.ltd/contact-moulding-optimisation/

By creating an account, placing an order or using our services, you agree to these Terms.

Use of SIM Workbench® and the Cav-Bal® Correction Engine is also governed by the End-User Licence Agreement presented during installation. The End-User Licence Agreement governs installation and use of the software. These Terms govern the website, account, purchase and related services.

If purchase terms conflict with the End-User Licence Agreement, the purchase terms control only the commercial matter they specifically address. Mandatory legal rights take priority over both documents.

2. Eligibility and accounts

You must be at least 18 years old and legally capable of entering into a contract.

You agree to:

  • Provide accurate and current account information.
  • Keep your password confidential.
  • Take reasonable steps to prevent unauthorised account access.
  • Notify us if you believe your account or Activation Code has been compromised.
  • Use the website and services lawfully.

You are responsible for activity carried out through your account unless it results from our failure to protect the service appropriately.

We may require a website account to access a download page, obtain support or manage a purchase. Use of SIM Workbench’s free desktop functions does not require a paid licence or in-application account sign-in.

3. SIM Workbench

SIM Workbench is a Windows desktop application containing tools for Scientific Injection Moulding studies, recording, analysis, graphing and reporting.

The standard SIM Workbench functions are supplied free of charge. No payment or Cav-Bal Activation Code is required to use those free functions.

We may maintain, change or discontinue free functions where reasonably necessary for security, compatibility, legal compliance or product development. This does not permit us to remove an existing paid fixed-term entitlement before its stated expiry without a valid contractual or legal reason.

4. Cav-Bal Correction Engine

The Cav-Bal Correction Engine is an optional paid feature within SIM Workbench. It provides proprietary cavity-balance correction calculations, including calculated hot-runner tip-temperature corrections.

A Cav-Bal entitlement may be provided as:

  • A free trial.
  • A paid fixed-term licence.
  • Another entitlement expressly described at the time of supply.

An active entitlement controls access to the Cav-Bal correction calculations. Cavity Balance measurement, analysis and compatible saved-study files remain available through the free SIM Workbench functions, subject to the software version and End-User Licence Agreement.

5. Free trials

We may offer a Cav-Bal trial without requiring payment information or a website login.

A trial:

  • Begins when it is activated through the software.
  • Applies to the installation or computer recognised by the licensing system.
  • Ends on the expiry date returned by the licensing server.
  • Requires online verification when SIM Workbench starts.
  • Cannot normally be restarted by reinstalling the software, deleting local files or changing the computer clock.
  • May be revoked where there is fraud, misuse, circumvention or a security concern.

The duration shown by the software or licensing server applies to that trial. We may change, suspend or withdraw the trial offer for future users. This will not retrospectively shorten a trial already issued unless there is misuse, a security requirement or another lawful reason.

A trial is provided for evaluation and does not guarantee that the software will meet every process, production or regulatory requirement.

6. Activation Codes and authorised computers

A purchased Cav-Bal licence is supplied through an Activation Code or another method stated at purchase.

Activation Codes:

  • Must be kept confidential.
  • May be used only for the licence and permitted number of computers.
  • Must not be published, sold, shared or transferred without our written permission.
  • Must not be used to avoid licence dates or computer limits.

The licensing system records authorised installations using cryptographic, pseudonymous device identifiers.

A licence may limit:

  • The number of computers currently authorised.
  • The total number of different computers that may be authorised.
  • The start or expiry date.
  • The products or features enabled.

If a computer is replaced, contact us or use the available licence-management process. We may revoke an old activation or increase a permitted replacement limit where appropriate.

If an Activation Code is lost or compromised, we may issue a replacement. A replacement code invalidates the previous code for future activations. Existing computer activations may remain authorised unless separately revoked.

7. Online licence checks

Cav-Bal requires a successful online licence or trial check when SIM Workbench starts.

If the computer cannot contact the licensing server:

  • SIM Workbench’s free functions remain available.
  • Cav-Bal correction calculations remain locked for that startup.
  • Existing study files can still be opened and viewed using the functions available without an active Cav-Bal entitlement.

A temporary internet, hosting or licensing-server interruption does not extend a licence or trial.

You should not rely on the licensing service remaining continuously available for safety-critical or production-control purposes.

8. Licence duration and expiry

A paid entitlement lasts for the period stated in the order, invoice, account, Activation Code email or licensing record.

The licence may begin:

  • On the purchase date.
  • On first activation.
  • On another date expressly stated in the order.

When the licence expires, Cav-Bal correction calculations become unavailable. The free SIM Workbench functions and compatible saved files remain available.

A licence described as fixed-term does not renew automatically unless automatic renewal is clearly stated before purchase and you expressly agree to it.

Expiry reminders are provided as a convenience. Failure to receive a reminder does not extend the entitlement.

9. Orders and payment

Prices, licence duration, VAT treatment and included features are shown on the applicable quotation, invoice, order or checkout page.

You agree to provide accurate billing and payment information.

Payment may be processed by an independent payment provider. That provider’s terms and privacy information also apply to its services.

We may delay issuing or renewing an entitlement until payment has cleared.

Where an order is agreed by quotation or invoice, the quotation or invoice forms part of the contract and controls the commercial details it specifically addresses.

10. Renewal and cancellation

A fixed-term Cav-Bal licence ends on its stated expiry date unless renewed.

If an automatically renewing option is offered, the renewal frequency, price, cancellation method and applicable notice will be clearly presented before purchase. You may cancel future automatic renewal using the method stated at purchase.

Cancelling renewal prevents future renewal charges. It does not normally terminate the entitlement period already purchased.

If a payment is cancelled, charged back or remains unpaid, we may suspend or revoke the related entitlement after considering the circumstances and any applicable legal rights.

11. Consumer cancellation and refunds

Nothing in these Terms removes statutory consumer rights.

If you purchase as a consumer at a distance, you may have a legal right to cancel within 14 days, subject to the rules applying to digital content and services.

Where you expressly request immediate access to digital content during the cancellation period, we may ask you to:

  • Consent to supply beginning immediately.
  • Acknowledge when the statutory cancellation right will be affected or lost.
  • Confirm the purchase accordingly.

Your cancellation right is affected only where the legal requirements have been met.

If digital content is faulty, misdescribed or does not meet applicable legal requirements, you may be entitled to repair, replacement, a price reduction or a refund under the Consumer Rights Act 2015.

Any statement that a payment is normally non-refundable does not restrict a refund or remedy required by law.

Business purchases do not have a general consumer cooling-off right. Refunds for business purchases are governed by the order, these Terms and applicable law.

12. Acceptable use

You must not:

  • Share, publish, sell or distribute an Activation Code.
  • Circumvent licence expiry, computer limits or online checks.
  • Falsify device, installation, payment or account information.
  • Interfere with the website, licensing server or another user.
  • Attempt unauthorised access to systems, accounts or data.
  • Introduce malware or carry out denial-of-service activity.
  • Use automated requests in a way that damages or unreasonably loads the service.
  • Use the software or service unlawfully.
  • Remove proprietary notices.
  • Copy, modify, reverse engineer or redistribute proprietary components except where applicable law expressly permits it and does not allow that right to be excluded.

Security research must not involve accessing other users’ information, disrupting the service or exploiting a vulnerability. Please report suspected vulnerabilities privately through our contact page.

13. Intellectual property

SIM Workbench®, Cav-Bal®, the Cav-Bal Correction Engine, associated software, calculations, designs, documentation, website content and branding are owned by Moulding Optimisation Ltd or its licensors.

The software is licensed rather than sold.

Your entitlement gives you only the rights expressly stated in the End-User Licence Agreement. No ownership of the software, source code, algorithms, trademarks or other intellectual property is transferred.

Third-party and open-source components remain subject to their applicable licences. Nothing in these Terms reduces rights granted by an applicable open-source licence.

Your study files and customer-entered engineering data remain yours or your organisation’s. We do not claim ownership of them merely because they were created or processed using SIM Workbench.

14. Engineering and safety responsibilities

SIM Workbench and Cav-Bal are engineering aids. They do not replace:

  • Competent professional judgement.
  • Machine, material and hot-runner supplier instructions.
  • Risk assessment.
  • Process validation.
  • Safe operating procedures.
  • Regulatory or quality-system requirements.

You are responsible for:

  • Checking that inputs and units are correct.
  • Confirming equipment and material limits.
  • Reviewing whether an output is plausible.
  • Independently validating settings before production use.
  • Applying appropriate safety controls.
  • Keeping suitable records and backups.
  • Deciding whether results are suitable for your equipment, products and regulatory obligations.

Do not use the software or its output as the sole basis for a safety-critical, medical, regulatory, product-release or production decision.

Stop and seek qualified assistance if an output appears unsafe, implausible or inconsistent with supplier information or observed behaviour.

15. Updates and availability

We may provide software fixes, compatibility changes, security updates or new versions.

SIM Workbench may check a public endpoint for update information and offer to open our official download page. The current update function does not silently install software.

Unless expressly agreed in writing, we do not guarantee:

  • A particular update schedule.
  • A particular support response time.
  • Continuous website or licensing-server availability.
  • That every feature will remain unchanged.
  • Compatibility with every future version of Windows or third-party software.

We will not use an update to remove a paid fixed-term entitlement before its stated expiry without a valid contractual or legal reason.

16. Support

Support is provided through the contact methods published on our website.

Unless a separate support agreement applies, support is provided on a reasonable-efforts basis without a guaranteed response or resolution time.

We may ask for information reasonably required to investigate a problem. Do not send confidential production or personal data unless it is necessary and you are authorised to do so.

17. Privacy

Our collection and use of personal information is described in our Privacy Policy:

https://mouldingoptimisation.ltd/privacy-policy/

The licensing service does not normally receive the contents of SIM Workbench study files, process values, graphs or reports.

18. Suspension and termination

We may suspend or terminate an account, service or Cav-Bal entitlement where reasonably necessary because of:

  • Fraud or attempted fraud.
  • Chargeback or non-payment.
  • A material breach of these Terms or the End-User Licence Agreement.
  • Sharing or misuse of an Activation Code.
  • Circumvention of licensing controls.
  • A security threat.
  • Unlawful use.
  • A legal or regulatory requirement.

Where the issue can reasonably be remedied, we will normally provide notice and a reasonable opportunity to remedy it.

Immediate action may be taken where necessary to protect users, systems, intellectual property or legal rights.

Suspension or termination does not affect accrued rights, existing payment obligations or provisions intended to continue after termination.

You may stop using the services at any time. You may end software use by uninstalling it and deleting copies under your control, subject to any record-retention obligations applying to you.

19. Warranties and statutory rights

Nothing in these Terms excludes rights or remedies that applicable law does not allow us to exclude.

If you are a consumer, digital content must comply with applicable rights under the Consumer Rights Act 2015, including applicable requirements concerning satisfactory quality, fitness for a particular purpose made known to us and conformity with description.

Subject to mandatory rights and express written commitments, the website, free services and software-related services are supplied “as available”.

Engineering results depend on matters outside our control, including:

  • Input accuracy.
  • Study method.
  • Process stability.
  • Equipment condition.
  • Material behaviour.
  • Measurement quality.
  • Professional interpretation.

We do not guarantee that every calculation or output will be error-free or that using the software will produce a particular production, commercial, quality or regulatory result.

20. Liability

Nothing in these Terms excludes or limits liability for:

  • Death or personal injury caused by negligence.
  • Fraud or fraudulent misrepresentation.
  • Any obligation that cannot lawfully be excluded or limited.
  • Any other liability that applicable law does not permit us to exclude or limit.

If you use the services in the course of a business, subject to the paragraph above:

  • We are not liable for loss of profit, revenue, business, contracts, anticipated savings, production, use, goodwill or data; business interruption; product recall; wasted material; or indirect or consequential loss.
  • Our total aggregate liability arising from the affected service, purchase or entitlement is limited to the greater of:
    • the fees paid directly to us for the affected service or entitlement during the 12 months before the event giving rise to the claim; and
    • £100.
  • These limitations apply only to the extent that they are reasonable and lawful.

If you are a consumer, we are responsible for loss or damage that is a foreseeable result of our breach or failure to use reasonable care and skill. We are not responsible for business losses resulting from consumer use.

Mandatory statutory rights and remedies remain unaffected.

21. Changes to these Terms

We may update these Terms to reflect changes in law, security, payment arrangements or our services.

The revised Terms will apply from the effective date shown when published.

A change will not retrospectively remove accrued rights or shorten an existing paid fixed-term entitlement.

Where a material change requires fresh acceptance, we will request it through the appropriate website, purchase or software process.

The version of the End-User Licence Agreement accepted during installation continues to govern that installation unless a later agreement is validly accepted.

22. General provisions

If a provision is unlawful or unenforceable, it will be treated as modified to the minimum extent necessary. The remaining provisions will continue.

A delay in enforcing a right is not a waiver.

You may not transfer a purchased entitlement without our written consent unless applicable law gives you a non-excludable right to do so.

We may transfer our rights and obligations to a successor to the relevant business, provided this does not reduce your rights.

No person other than you and Moulding Optimisation Ltd has a right to enforce these Terms under the Contracts (Rights of Third Parties) Act 1999.

Neither party is responsible for delay caused by events outside its reasonable control, except that this does not remove obligations to pay amounts already due or responsibilities that cannot lawfully be excluded.

23. Governing law and courts

These Terms are governed by the law of England and Wales.

If you use the services for business purposes, the courts of England and Wales have exclusive jurisdiction, although either party may seek urgent protective relief in any competent court.

If you are a consumer, the courts that have jurisdiction under applicable consumer law may hear a dispute. If you live in Scotland or Northern Ireland, you may also bring proceedings in your local courts.

Nothing in this section deprives a consumer of mandatory protection under the law of the country in which they live.
