The Silicone Moulding Production Process

All phases of the silicone product development process, including product design, precision tooling, manufacturing, and fulfillment, take place at LGDSilicone under one roof. ​

The silicone molding production process begins with silicone raw material selection. Silicone rubber materials are formulated to meet different application needs, so they are divided into Different Options.
silicone raw material selection
For a new silicone product to succeed, the silicone material must be chosen carefully.
We can recommend the optimum silicone material by properly assessing the needs of our customers. The most practical material will be chosen based on the product’s structure and function, the application environment, performance, safety test requirements, and the customer’s budget.
Without any elasticity or strength, silicone is a milk-white or transparent gum-like component as its basic material. Silicone material is combined with a variety of components, such as vulcanizing agent, reinforcing filler, accelerator, colorant, etc., to increase its properties and get the desired color.
Silicone compounding is the complex technology of selecting and blending silicone with other ingredients. The proper mixture is crucial to the success of silicone molding production.


Silicone material after blending will be collected in large rolls covered with film to prevent dust or dirt. It then will be cut into slices by an automatic cut machine. The slices’ length and width will be controlled according to the silicone part’s weight to be molded. Silicone blanking makes it easier for our molding operators to weight the material during silicone molding production.

Molding operators should be able to cut slices into small pieces and weight accurately, then place them quickly onto the tool mold in right place. Material weight is crucial, as too much material will lead to silicone parts size increase, and lack of material will cause small size or missing part.
Silicone molding production place the material
LgdSilicone offers standardization training to each molding operator, all our molding staffs have at least 3 years of work experience in silicone molding production. Their years of experience allow them to solve any manufacturing problems in silicone molding, and ensure reliable and high-quality outcomes.


Silicone material will be fully cured under high temperature and pressure from vulcanizing molding machine, then the silicone parts are formed. Our molding department is equiped with 8 high precision automatic vacuum vulcanizing machines which can be used to craft more high performance silicone parts. Our sophisticated molding machines, coupled with our skilled operators, provide the capacity and flexibility to mould high-quality, high-volume silicone parts in short peroid.


The vulcanizing molding machine will automatically relieve pressure after the silicone is fully cured, allowing molding personnel to remove the silicone-molded pieces by pulling out the tool mold. The raw material will be repositioned for the following vulcanization cycle.


Silicone Flash – Is a thin flap of material at the parting line where the mold splits. Due to the low viscosity of silicone material and high molding pressure during heating and curing, The pressurized silicone material will flow to every spaces of tool mold. Flash can be minimized with favorable designs and better tooling and accurate material weight during vulcanizer molding production. Flash will be removed mainly by hands, cryogenics deflashing can also be applicated for some cases.

Custom Silicone Mold FAQs

  • 5 years of plastics injection molding set-up and processing experience
  • Experience with robotic load/unload/packing equipment is highly preferred
  • Hand-on set-up related experience with plastic injection molding machines, cranes, various hand tools, temperature controllers, drill press, tapping arms, pick and place robots, etc.

Injection molding of liquid silicone rubber is a process to produce pliable, durable parts in high volume. Liquid silicone rubber is a high purity platinum cured silicone with low compression set, great stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts, where high quality is a must. Due to the thermosetting nature of the material, liquid silicone injection molding requires special treatment,

Injection molding is a manufacturing process commonly used for fabricating items from plastic trinkets and toys to automotive body parts, cell phone cases, water bottles, and containers. Essentially many of the plastic parts that we use in every-day life are injection molded.

The cost of a silicone mold or tool depends on the requirements of your product. Before you can get pricing, you must have an engineered design. Laminar Industries can help streamline the quote for you. Pleas contact us at and we’ll be happy to help point you in the right direction.
