Which type of silicone rubber should you use, HCR or LSR?There are 4 main types of silicone rubber: RTV: Room Temperature vulcanizationHTV: High Temperature VulcanizationHCR: High Consistency RubberLSR: Liquid Silicone RubberFor Room Temperature vulcanization Silicone and Liquid Silicone Rubber, the
Mold structure of silicone rubber products:A. The upper limit of mold thickness, tentatively set at 250mm, can be up to 500X500 in size, and the product can be up to 400X400 in the mold area.The mouldThe structure is generally divided into upper die, lower die, bottom plate, top plate, ejector rod,
Silica gel used in food is an inorganic polymeric colloid material formed by polycondensation of silicic acid. The main ingredient is SiO2·nH2O, with a content of over 98%, no toxicity, no taste and stable chemical performance. Under normal conditions, it does not react with any acid-base salt excep
Why choose LSR injection molding/mould
Better Silicone.Liquid Silicone Rubber is a highly desirable material for medical applications because of it's sterilizability and chemical resistance.LSR molding has the ability to produce parts with undercuts. Many simple undercuts can be easily removed by the press operator without mechanical assistance. Each part will be reviewed on a case by case basis for feasibility.
Liquid Silicone Rubber Injection Molding design
Thermoset liquid silicone rubber (LSR) liquid injection molding structure is similar to thermoplastic rubber molding structure on the whole, but there is still difference between both of them.
LSR material usually has a lower viscosity, contributing a short time for injection molding, so it is, even under a fairly low injection pressure. A good venting device plays an important role in mould for avoiding air entrapment.
Besides, LSR materials don’t shrink in molding like the thermoplastic rubber do and they usually tend to expand with heat while shrinks slightly with cold. Therefore the liquid silicone rubber products won’t stay in molding convexity as expected but in cavity with larger surface area.
Silicone Rubber, liquid silicone rubber and solid silicone rubber included, is an elastomer compound for liquid silicone rubber injection molding or silicone rubber compression molding, which are widely used in automotive applications, food storage products, electronics, infants products and medical devices due to non-reactive, elongation, tear strength, resistance to extreme environments and temperatures, and so on .
