Medical Silicone Rubber Compression Molding
Medical Silicone Molding, which well known as silicone rubber compression mold and liquid silicone rubber injection molding ( LSR Injection molding ), as a tooling to produce medical silicone products or parts.

Compression moulding is one kind of elastomer molded process, which heat up of thermoplastics and thermoset resin (free-flowing granular form or a viscous material) in heated mould cavity & chamber in aim to fabricate desired molded elastic parts or products by hydraulic press,

Silicone compression moulding process is also called vulcanization process, is performed at a mold temperature of 350 °F and mold pressure of 100 psi (180 °C and 700 kPa) with curing time of 3 min. After the material is cured, the mold is opened and the elastomer rubber is pushed out.

Compression molding is a low-cost process and is capable of high volume production.

If not special demands about silicone durometer/hardness (shore A), production environment, large quantity, or high precision, most medical company mainly choose medical  silicone compression molding as lower mold-making cost. This kinds silicone is medical solid silicone.

Notes: Solid silicone can be made by injection moulding, which mostly suit to big silicone products like silicone ball etc. Solid silicone injection molding than rubber molding making cost is expensive than solid silicone rubber compress molding, however, per unit cost is a little lower.


Medical Liquid silicone Rubber injection molding
Liquid silicone rubber injection molding mainly suit to durometer demands, mass production or 100,000 grade clear room, which mold-making cost is expensive as need cold runner, good mold steel and much mold-making process.

The differences between liquid silicone rubber and solid silicone rubber
Silicone rubber can be divided into two types according to the form of existence, liquid silicone rubber and solid silicone rubber. Because of different forms of existence, they have distinct physical performances, which also results in significant differences in application. This article will discuss the differences between the liquid silicone rubber and solid silicone rubber.

Vulcanized silicone rubber products and mixed silicone rubber are solid. The solid silicone rubber we mention here is mixed silicone rubber, which is also known as high-temperature silicone rubber. This kind of silicone rubber can only be completely vulcanized in high temperature no matter which kinds of vulcanizing agent is used in order to get the ideal physical performance. Solid silicone rubber can be made into all kinds of silicone products after vulcanization, which generally have good physical properties. Solid silicone rubber can reach food grade standard by FDA approval after two-times vulcanization process. Thus, solid silicone rubber can be applied in both industry and foodstuff.
LSR has more variety, and it is liquid because it is made of original organic silicone material. Owing to the sulfur of movement, LSR is easier to form, so it can be easily made into mould used to copy product, which is what solid silicone rubber unable to meet. Moreover, it can also be made into adhesive being adhered to a variety of materials. The majority of LSR can be
vulcanize at room temperature.
LSR can be divided into
condensed type and addition type according to the reaction types. The former generally can not reach the food grade standard while the latter can do. Therefore, addition type LSR is used in all walks of life because of its very good physical properties.

Quickly Quotation Demands:
1.2D/3D designs Drawings, Samples, or other basic information
2.Materials Demands:
3. Surface and Shore A Demands.
4. Sizes Tolerance Demands: +/-0.005mm - +/-0.3mm

Notes:
1. Our company will not sell any silicone/LSR mask mold tooling to customers. Just accept orders which make-mold tooling and produce mask together.

2. Our company will not sell any ready silicone/LSR mask to other persons without our customer's permission
