The procedure of silicone parts manufacturing is shaded tooling through the manufacturing indirect mold process. If the made is compared to the procedure of ordinary steel, the material such as epoxy resin, or silicone rubber, of such molds is a bit softer. In common, the volume production of shaded mold is around 50 to 500 pieces.

Few features of silicone rubber molds

Below are some of the processing flow and properties of silicone manufacturing:

  • It is one of the most famous methods of manufacturing
  • It comes along with ideal elasticity and flexibility, it can also create parts that have complex designs, deep grooves, negative angles, draft angles with no mold, and also with fine patterns.
  • Such kind of mold has not a very long cycle of production and assures standard quality.
  • The price of this material is relatively high. But in tiny volumes, this material reckons for several rates of silicon parts manufacturing, particularly for the manufacturing of 1 PC and huge size.

Due to these reasons, several research has been conducted on the subject of how to economize the consumption of material silicone rubber in this type of technical process and still generate examples that fulfill the needs at the exact time. For instance, below are some of the steps of silicone parts manufacturing.


  • Sample of part or you can even say prototype.
  • Then add the clay structure or the paste of plasticine
  • Then add some slurry of plaster and permit it to shape and solidify
  • Detach clay
  • Now, add silicon material
  • Now, that your end product is ready for trial manufacturing, you can also repair it if required

These are a few simple steps you need to follow.

Ideal features of silicone rubber mold

Below are a few of the finest properties of this rubber mold:

  • It consists of better strength, and stimulation and has a bit less shrinkage.
  • It is simple to create elastic molds with the help of this material, as it doesn't need any high-level technology, or pieces of equipment, it requires only some hours to get completed at room temperature.
  • Such molds are reusable and can hold brutal operations, they can also secure the prototype and manage precision tolerance of product batch manufacturing, allow you to create nexus parts and shapes, and no grinding and milling procedure is required. The process of remolding is also very serene, making less the cycle of production mainly of a large product, and the modification of mold is also very simple.
  • As it contains ideal concave and convex parts and elasticity, it can be straightly smothered out after the process of pouring molding, which is known as very distinct.

These are some excellent features of silicone rubber molds.

General applications

  • Production of low-volume
  • Tooling of bridge
  • Pilot runs
  • Functional prototyping

Final words

Hence, silicone parts manufacturing is an immense alternative in the prototype phase to gain speed, precision, and sample of low-cost acquisition. This article has all the information relevant to silicone parts manufacturing.
