Silicone Compression Molding

Solid Silicone Molding Process:

Solid Silicone Products Are Usually Added By High Temperature Mold (Double 25 Or Double 24) Silicone Vulcanizing Agent Of The Compound, And Then Through The Plate Vulcanizing Machine Pressure, High Temperature Sulfur Into Solid Molding, Molded Silicone Hardness Is Usually In (Shore Hardness)30-70A. In The Process Of Rubber Mixing Production In Silicone Factory, The Raw Rubber Is First Added To The Double Roll Rubber Mixer Or Closed Kneader And Gradually Added White Carbon Black, Silicone Oil And Other Additives Repeatedly Refining. According To The Different Fillers And Additives, The Performance Of Silicone Is Also Different.


The Molding Of High Temperature Silicone Has Two Kinds Of Molding And Extrusion Process, The Corresponding Silicone Material Is Divided Compression Silicone And Extrusion Silicone , Each Molding Process Has Its Own Advantages And Disadvantages, In Order To Help You To Choose Suitable For Their Own Molding Process Of HTV High Temperature Silicone Raw Materials, The Following Summarizes The Difference Between Solid Silicone Molding And Extrusion Molding Process:


》Molding Machine

Compression Silicone Is Molded By Vacuum Vulcanizing Machine, And Extruded Silicone Is Molded By Extruder.


Curing Agent

Compression Silicone Can Be Added By Adding Odorless Vulcanizing Agent Or Double 25 Vulcanizing Agent After The Piece Cut Strip, Strip/Sheet Silicone Raw Materials Into The Machine After High Temperature Vulcanization Molding; And Extruded Silicone Is By Adding Double 24 Curing Agent Or Platinum Curing Agent, Directly Throw The Whole Piece Of Silicone Raw Materials Into The Rubber Bucket After Extrusion Curing Molding. Compression Silicone And Extruded Silicone Rubber Can Reach Food Grade, Molded Silicone Rubber To Reach Food Grade Must Add Odorless Vulcanizing Agent, And Extruded Silicone Rubber To Reach Food Grade Must Add Platinum Vulcanizing Agent.


》Rate Of Forming

The Molding Time Of Compression Silicone Needs 60s-180s, And The Molding Time Of Extruded Silicone Only Needs A Few Seconds.

In Conclusion, Compression Silicone Is Suitable For Silicone Products With Limited Shape And Size, While Extruded Silicone Is Suitable For Silicone Products With A Certain Shape And No Length Limitation.


Compression Silicone Raw Materials By Adding Curing Agent Can Be Saved For About a Month, And Extrusion Silicone Raw Materials By Adding Curing Agent Can Only Be Saved For About 3 Days, If The Two Do Not Add Curing Agent Can Be Effectively Preserved For a Year.
