Silicone Rubber Molding
Producing your silicone rubber parts by silicone rubber moulding process.
Custom Silicone Rubber Molding Services
With a successful track record as a highly respected silicone rubber molding manufacturer, Rapid-MFG Silicone Rubber Molding has a long history of being a supplier of top-quality custom-molded products. We are equipped to handle a wide range of silicone rubber materials, from elastomers and silicone to neoprene, NBR, and EPDM. We adhere to precise tolerances of (±) 0.005 inch and specialize in the three most common rubber molding operations: compression, injection molding, and transfer.
Known for its extreme durability and elasticity, silicone rubber performs well in applications that require robust operation in high-pressure environments or under extreme deformation conditions. And with the ability to manufacture high-performance products composed of this durable material, we have been pleased to meet the needs of several industries, including aerospace, electronics, and medicine.
At Rapid-MFG, we are determined to provide our customers with superior products that meet the industry’s high standards. We invite you to contact Rapid-MFG to inquire about any of our additional service options, including rubber-to-metal bonding, anodizing, and rapid prototyping. From aircraft and mechanical components to custom seals and insulators, we offer superior custom silicone rubber molding products and services.
Types of Silicone Rubber Molding
We offer two different types of custom silicone molding: LIM (Liquid Silicone Injection Molding) and compression molding. What makes these two types different is the technology, process and machine that is used to mold the parts. While both processes are great options your part geometry and complexity will likely determine which process to use. Here is some more information on each process:
LIM Silicone molding:
Also known as LSR silicone molding (Liquid Silicone Rubber), this is a liquid injection molding process, where a high-viscosity liquid comes in two parts, Part A and Part B is loaded into the molding machine. The machine mixes the two parts just before it is injected into the mold cavity, where a chemical reaction causes it to cure very quickly. After the part is cured the part is either ejected or manually pulled from the mold.
Compression molding:
The process involves placing a silicone rubber sheet onto a heated mold cavity. The rubber sheet is compressed between the two mold halves and fills to the mold cavity due to heat and pressure. The part is allowed to cool and is removed from the mold. Compression molding has some distinct benefits including lower molding and manufacturing costs. This makes compression molding the ideal choice for parts with low to medium complexity such as o-rings and sealing gaskets.

Understanding the Differences Between CNC Milling and CNC Turning
CNC milling is employed for greater precision, while CNC turning is chosen for higher efficiency. What is CNC Milling?CNC milling involves using a rotating cutting tool to remove material from a workpiece. The workpiece is typically held stationary on a table, while the cutting tool moves in multiple axes—usually along the X, Y, and Z […]
