Custom Silicone Molding Solution
Zhongren specializes in custom silicone molding, delivering precision components designed for durability, flexibility, and thermal stability. With extensive expertise, we produce parts that meet strict performance and regulatory requirements.
Silicone’s excellent biocompatibility, electrical insulation, and chemical resistance make it well-suited for medical, automotive, food-grade, and consumer applications.
How Are Silicone Rubber Parts Manufactured?
We utilize the following silicone molding methods, selected based on part geometry, volume, and performance needs:
- Silicone Injection Molding
- Silicone Compression Molding
- Silicone Transfer Molding
- Silicone Overmolding
Successful silicone molding requires accurate temperature control and precise curing to ensure full crosslinking. Proper venting and clean material handling are essential to prevent defects and maintain part quality.

FAQ with Silicone Rubber Molding
What's the difference between silicone injection molding and compression molding?
Injection molding is ideal for high-volume, complex parts with tight tolerances. Compression molding is more suitable for larger, simpler parts or low-volume production.
Do you support medical-grade or FDA-grade silicone molding?
Yes, we offer silicone rubber injection molding using certified medical or food-grade materials.
What's your typical lead time for custom molded silicone parts?
Depends on tooling complexity, but generally 2–4 weeks from final design approval.
