Gaskets & Seals Manufacturing Process
Below are the processes when we fabricate the gaskets and seals:
Gaskets & Seals Design
Before making the gaskets or seals, we must confirm if your design is ok. And we can assist you in making a design.
Making The Die-cut Mold
After the gaskets or seals design is confirmed, we will use CNC machine to make a die-cut mold.
Punching The Larger Sheet
After the mold is done, all the gaskets or seals will be made from silicone or rubber materials sheets.
Our QC team will check all the gaskets and seals to ensure they are of the required quality.
Usually all the gaskets and seals are packed with plastic bags, but we can also use other packaging if needed.
After the goods are packed, we will ship them by air or by the ocean as per your requirements.

What is a silicone rubber gasket?
Silicone rubber gaskets provide superior performance in all types of applications. These high-quality materials can withstand extreme temperatures, perfect for any application where leak prevention is necessary!
Is silicone gasket better than rubber?
Silicone is superior to natural rubber in terms of resistance against hydrocarbon fuels and lubricants. For this reason, it’s often the go-to material for chemical seal applications that require protection from highly corrosive fluids such as those found outdoors or on machinery where rust will do no good!
What are the silicone gasket & seal applications?
Think of silicone rubber gaskets as the coating protecting your important parts from outside elements. Industries use these innovative materials for various applications, such as insulation and sealants in electrical or aerospace engineering; keyboards on office machines; surgical gloves, which must be highly biocompatible (meaning they won’t cause any harm if eaten).
Can i get a custom gasket sample before place the order?
Sure, we can offer samples for your evaluation and test, sample usually will take 3-7 days. And it will be charged because we have to make a sample tooling for them.
