Customization Process

A clear, step-by-step workflow from initial consultation to delivery and after-sales support.

1

Initial Consultation & Requirement Analysis

We start with a detailed discussion to understand your product specifications, performance needs, and application environment.

2

PI & PO Confirmation

Formalize the project scope, pricing, and delivery terms with a Proforma Invoice (PI) and Purchase Order (PO) to set clear expectations.

3

Requirement Confirmation & Material Selection

Finalize technical requirements, including material grade, hardness, color, and certifications to ensure compliance and performance.

4

Design Proposal & Prototyping

Our engineering team develops a detailed design proposal and creates functional prototypes for your review and testing.

5

Design Confirmation & Tooling

Once the prototype is approved, we proceed with precision mold design and manufacturing to ensure consistent, high-quality production.

6

Mass Production & Quality Control

Using advanced injection molding and compression molding equipment, we execute production while conducting rigorous in-process inspections.

7

Final Inspection & Packaging

Every finished product undergoes a final quality check before being carefully packaged to prevent damage during transit.

Frequently Asked Questions

1

How do you protect my proprietary designs and intellectual property?

+

We treat your intellectual property (IP) as our highest priority. We are fully prepared to sign a bilateral Non-Disclosure Agreement (NDA) before you share any 2D/3D drawings, ideas, or physical samples. Our internal engineering department operates under strict data security protocols, ensuring that your product files are only accessible to authorized project personnel. We never showcase, sell, or replicate our OEM/ODM customers' proprietary products under any circumstances.

2

How do you charge for custom silicone mold tooling, and who owns the mold?

+

Mold tooling cost is quoted based on product complexity, size, cavity count, and required mold life. The tooling fee is a one-time charge. Once paid in full, the mold is owned by your company and is exclusively used for your production. We store molds in our facility at no additional cost and can produce reorders at any time using your existing tooling.

3

What is your Minimum Order Quantity (MOQ) for custom silicone products?

+

MOQ varies by product type, size, and manufacturing process. For standard silicone parts, typical MOQ starts from 500–1,000 pieces. For complex or large items, the MOQ may be higher. We understand that new product launches often require smaller trial runs, and we are flexible in discussing pilot production quantities to support your market testing.

4

Are your silicone materials compliant with FDA, LFGB, and other international standards?

+

Yes. We offer a range of silicone materials that comply with FDA (US), LFGB (Germany/EU), RoHS, REACH, and other relevant standards. Material compliance certificates can be provided upon request. For food-contact and baby products, we recommend specific food-grade materials and can arrange third-party testing for your project if required.

5

What is the typical lead time from prototype to mass production?

+

Prototype development typically takes 7–15 days depending on complexity. Mold manufacturing takes 15–25 days after design confirmation. Mass production lead time is generally 15–30 days after sample approval, depending on order quantity and production scheduling. For urgent projects, we can discuss expedited options to meet your timeline.
