What is Compression Molding?

Compression molding is also known as hot press molding or heat press molding, it is a manufacturing process that involves the use of heat and pressure to mold a material into a specific shape. In the case of silicone products, the material is typically a silicone rubber material. The process begins with the raw material being placed into a heated mold cavity. The mold is then closed and pressure is applied to compress the material into the desired shape. The heat and pressure are maintained until the material has cured and solidified into the desired shape.

Compression Molding Silicone Products

Compression molding is a highly versatile and effective technique for the manufacturing of silicone rubber products. It allows for the production of high-quality products with consistent dimensions and properties, and can be used to produce a wide range of products with varying durometers and hardness levels. As such, it is a popular choice for manufacturers across a range of industries, from industrial components to consumer goods and medical devices.

Discover the Pros and Cons of Compression Molding for Silicone Products - Make an Informed Decision


Compression molding offers several advantages over other molding techniques, making it a preferred choice for many custom silicone products.


One of the key advantages of compression molding for silicone products is the low material cost. One one hand, comparing to liquid silicone, the material costs are lower, on the other hand, the molding process involves the use of pre-cut silicone sheets or pellets, which can be easily molded into the desired shape.

Compression molding also does not require the machine to be cleaned for colored products. This is because the process involves the use of pre-colored silicone sheets or pellets. This eliminates the need for cleaning the machine between runs, saving time and reducing the risk of contamination.


Another advantage of compression molding is the low mold cost. Unlike other molding techniques, compression molding does not require expensive molds to be created. This is because the process involves the use of simple molds that can be easily fabricated using low-cost materials. This makes the process more accessible to small and medium-sized businesses that may not have the budget for expensive molds.


Compression molding is an excellent choice for silicone products manufacturers who looking to produce high-quality silicone products at a lower cost. With its low material and mold cost, easy-to-clean process for colored products, and ability to produce complex shapes quickly and consistently, it is no wonder that compression molding is a popular choice for silicone product manufacturing.


Though, compression molding is a widely used technique for manufacturing custom silicone products. However, like any other manufacturing process, it has its own set of disadvantages as follows.


  • High Molding Temperature

Compression molding requires high molding temperature, usually around 160℃ to 180℃, when to be overmolded with other materials, it requires the other material have to be high temperature resistant, otherwise it may cause degradation of the material, leading to poor quality products.


  • Long Curing Time

Another disadvantage of compression molding is the long curing time. The curing process is essential to ensure that the silicone material sets and retains its shape. However, the curing time for compression molding is longer than other molding techniques, such as LSR injection molding. This can lead to longer lead times, which can be a disadvantage for customers who require quick turnaround times.


  • More Burrs and Waste Materials

Compression molding can also result in more burrs and waste materials. During the molding process, excess material can be squeezed out of the mold cavity, resulting in burrs or flash around the edges of the product. This can be time-consuming to remove and can result in wasted material, which increases the cost of production.


  • Large Parting Lines

Finally, compression molding can result in large parting lines. Parting lines are the visible seams that appear on the surface of the product where the two halves of the mold meet. These lines can be unsightly and can affect the overall appearance of the product. In addition, large parting lines can be difficult to remove, which can increase the cost of production.


It is essential to consider these disadvantages when choosing a manufacturing process for custom silicone products.
