Liquid Silicone Rubber (LSR) Injection Molding

Liquid Silicone Rubber (LSR), Is a Popular Product For Consumers And Silicone Manufacturers. It Has Good Elasticity, Waterproof And Moisture-Proof Properties, And Is Resistant To Acid, Alkali And Other Chemicals, So It Is Generally Used To Replace Plastic Products In Daily Life. Liquid Silicone Is Divided Into A Glue And B Glue, The Ratio Of The Two Is 1:1 Controlled By The Quantitative Device, And Then The Static Mixer Is Fully Mixed, Injected Into The Injection Pipe And Then Injection Molding Production.

LSR Is a Non-Toxic, Heat-Resistant, Highly Resilient Flexible Thermosetting Material With Excellent Transparency, Tear Strength, Resilience, Yellowed Resistance, Thermal Stability, Good Air Permeability, Heat Aging Resistance And Weather Resistance. Its Rheological Behavior Is Characterized By Low Viscosity, Fast Curing, Shear Thinning And High Coefficient Of Thermal Expansion. LSR Is a Double Liquid Fast Vulcanizing Material With Platinum As Catalyst, Which Can Be Produced By Injection Molding In Large Quantities, Fast Vulcanizing And Repeatable Machinery. It Is Also One Of The Raw Materials Often Used By Supluck Silicone.

Forming Process

Liquid Silicone Rubber Injection Molding Technology (Lim) Is a New And Efficient Silicone Rubber Molding Method Developed In The Late 1970s. It Is a New Silicone Rubber Molding Processing Technology Formed By Combining Liquid Silicone Rubber With Equipment That Can Accurately And Stably Complete Injection Molding. Only Two Components (Can Also Include Auxiliary Components Such As Color Matching) Into The Equipment, From Feeding, Metering, Mixing To Molding Automatic Completion. This Processing Technology Can Achieve The Purpose Of Simplifying The Process, Shortening The Processing Time, Saving Materials And Improving Efficiency. And The Production Process Basically Does Not Produce Waste, Conducive To Environmental Protection.

                                                                                                                                                                                                                                                                                    Through The Device, A And B The Two Liquid Silicone Rubber Raw Materials Are Precisely Measured And Transported To The Mixing Device → The Two Components Are Fully Mixed In The Mixer And Then Transported To The Injection Molding Machine → The Two Components Are Injected Or Sprayed Into The Preheated Multiple Molds By The Molding Machine And Evenly Distributed To Each Mold Cavity → The Silicone Rubber Material Is Heated And Quickly Vulcanized In The Hot Mold Cavity → The Mold Is Automatically Opened And Out After Vulcanization → Then The Mold Is Closed And Advanced Enter The Next Molding Cycle. The Whole Molding Cycle Of Tens Of Seconds To a Few Minutes, According To The Size Of The Different Molding Cycle Is Also Different.

The Whole Process Is Fully Automatic. After Setting The Parameters, No Manual Control Can Be Achieved To Improve The Production Efficiency.


Advantages Of Liquid Silicone Injection Molding:

 Save Manpower: Material Conveying, Metering, Mixing, Injection And Other Processes To Achieve Continuous Automation, Reduce Power Consumption.

Can Improve The Production Efficiency: Through Rapid Curing To Shorten The Molding Cycle.

Can Improve Product Quality: No Reaction Byproducts, Not Mixed With Impurities.

Suitable For Composite Molding: Due To The Good Fluidity Of The Material, Low Forming Pressure, Wide Curing Temperature Range, In Addition To The Insert Molding, Can Also Be Composite Molding.One - Time Molding, No Waste And Automation
