The production process of leak-proof silicone valve

Today, we’ll show you the production process of leak-proof silicone valve. Step 1: Whole piece: processed by liquid injection molding machine Step 2: Appearance Inspection: check whether there is dead material, pollution or lack of material Step 3: Trimming: manually remove defective burrs from the whole piece Step 4: Cross Slit Punching: the cross slit is processed by punching machine Step 5: Top out food grade talcum powder: use a jig to push out the talc powder Step 6: Shape punching: place the whole piece on the jig and punch into a single silicone valve Step 7: Spot check: sampling inspection Step 8: Dust removal: use an air gun to remove movable dirt from the product Step 9: Packing: Weigh the silicone valve, and pack into bags and boxes Thanks for your watching!

These trends on silicone will dominate 2022

Speaking of silicone products, you may know silicone is widely used in industries like electronics, beauty, medical, maternal and child, while do you know it’s also getting popular in Automotive ADB headlights? Comparing with plastic lenses, without coating, the light transmittance reaches to 94%, and the temperature resistance is from -40 to 150 Celsius degrees. After 3000 hours double 85 test (85℃/85% Humidity), the silicon lens is no changing. The silicone lens has better light transmittance and dispersibility, and stronger weather resistance, it’s also flame resistance. Comparing to Glass, silicone has great fluidity, which makes it suitable for complex or micro-structure designs. Our factory is very mature in producing LIM& LSR overmolding silicone lenses for LED lighting, welcome to contact us for technology discussion.

What's the 6 major elements for the production of silicone molding products

Do you know what's the 6 major elements for production of silicone molding products? For better understanding, our factory Yejia Silicone has taken the video, let's take a look!

Yejia Silicone Molding Factory

Today, let’s take a look at the different production workshops for these 3 kinds of silicone products. (1)Food grade silicone products processed by compression molding and LSR injection molding at our workshop I, such as, silicone valves, silicone covers, silicone gaskets and other custom silicone consumer products. (2)LSR injection molding medical grade silicone products are produced in ISO13485 certified workshop II, for example, medical silicone wound drainage ball. (3)Class 100,000 clean optical production workshop III produce optical grade silicone products, like optical silicon lens, LSR overmolded silicone optics, LED silicone lenses and so on. What’s more, we have set up the automatic punching production for silicone valves. If you are interested in custom silicone molded products, please contact us, we’re looking forward to hearing from you.
