Custom Components. Defined Requirements.
Develop a new component or replace an existing part with manufacturing support from CRYSTAL. We review geometry, dimensions, tolerances, material compatibility, and order quantities before proposing a production approach.
Design and Tooling Support
Work from technical drawings or a physical sample. Design review and prototyping, where required, help confirm fit and function before production.
Application-Based Material Selection
Select the compound according to temperature, contact media, hardness, mechanical loads, and environmental exposure. The material grade is confirmed against your specification.
Controlled Manufacturing
Choose the molding method, tooling, and inspection requirements to suit the component and production quantity. Confirm acceptance criteria before manufacturing begins.
From Drawing to Finished Component
1. Review Your Requirements
Share drawings or samples, dimensions and tolerances, operating conditions, quantities, and the required delivery schedule.
2. Confirm Design and Material
Review the component design and compound options. Agree on prototypes or samples when needed and confirm the production specification.
3. Prepare and Validate Tooling
Develop the mold and review trial parts against the agreed dimensional and functional requirements before releasing production.
4. Mold and Finish
Manufacture components using the selected process, such as compression or injection molding. Define trimming, finishing, or assembly requirements for the project.
5. Inspect and Document
Check finished parts against the agreed inspection plan. Dimensional checks, hardness measurements, and other testing are specified according to the application.
6. Pack, Deliver, and Support
Coordinate packaging, delivery, and any agreed documentation. For repeat orders, review the approved specification and any changes in operating requirements.
Material Options for Your Project
EPDM, NBR, natural rubber, silicone, and other compounds may be considered according to the application. Material names alone do not establish suitability: grade, formulation, temperature, contact media, and required approvals must be reviewed together.
Frequently Asked Questions
What is custom rubber molding?
It is the manufacture of rubber components using a mold and a material specification developed for a particular part. The design, dimensions, hardness, and operating requirements are defined for your application.
Can you work from a sample?
Yes. A sample can support dimensional review and reverse engineering when drawings are unavailable. Operating conditions and material requirements are still needed to assess the replacement design.
How is the rubber material selected?
Selection depends on the contact medium, temperature, hardness, movement, loading, and environmental exposure. Share any required standards or approvals so the proposed compound can be reviewed against them.
What affects price and lead time?
Part geometry, tooling, compound, tolerances, testing, and order quantity affect cost and timing. We confirm the quotation and schedule after reviewing the project requirements.
Can parts be made in a specific color?
Color options depend on the compound and application. Provide a reference sample or color code; the target shade and acceptance criteria should be agreed before production.
What should I include in my enquiry?
Include a drawing or sample description, dimensions, tolerances, material and hardness if known, operating conditions, quantity, and delivery location. Identify any testing or documentation requirements.
