Frequently Asked Questions

Q: What is the primary advantage of liquid silicone overmolding for gaskets?

Liquid silicone overmolding creates a permanent, seamless chemical bond with the plastic substrate, eliminating gaps where leaks occur and reducing the need for separate assembly steps.

Q: Can these silicone-coated gaskets be customized to specific dimensions?

Yes, we specialize in customized production. We can manufacture gaskets based on your specific technical drawings or physical samples to ensure a perfect fit for your application.

Q: Which industries typically use LSR overmolding products?

Our products are widely used in medical device manufacturing, automotive electronics, consumer wearables, and high-precision industrial equipment where sealing and durability are critical.

Q: How do you ensure the precision of the ±0.5mm tolerance?

We use high-precision CNC-machined molds and automated injection molding machines with real-time pressure and temperature monitoring to maintain strict dimensional control.

Q: Is the material used safe for medical or food-contact applications?

Depending on the project requirements, we can provide certified medical-grade LSR that complies with international safety standards for biocompatibility and non-toxicity.

Q: What is the typical lead time for a customized LSR gasket order?

Lead times vary based on complexity. Typically, mold design and sampling take 1-2 weeks, followed by mass production timelines based on the order volume.
