Silicone Extrusion Molding

Silicone extrusion is a cost-effective continuous molding process. With extrusion, you can achieve high-volume product output in a relatively short period. Silicone extrusion is the process whereby silicone is forced through a shaped die (a stainless steel disc with a pattern cut out) to produce cords, complex profiles, and cross-sections.

The silicone material is thermally cured through specific molds and equipment to form the required cross-section, complex contours, and continuous lengths.

Silicone rubber that is used via extrusion molding, either precipitated or fumed, is widely preferred as a material for various applications. This process is especially suitable for the production of unrestricted tubular or strips of silicone rubber products, such as:

  • medical silicone tubes, silicone wires, sealing strips, gaskets, or other complex-shaped products.
  • Extruded parts for industrial use and technical use, like silicone tubes, profiles, strips, electric cabling, etc.
  • Food contact products that complied with FDA 177.2600.

Our Extrusion Molding process produces custom prototypes and end-use production parts in 7 days or less. We use AL molds that offer cost-efficient tooling and accelerated manufacturing cycles, and stock various grades and durometers of Solid materials.

Custom Silicone Extrusions

Thanks to advances in production capabilities over the last 30 years, the custom silicone extrusion process has become more accessible. Subsequently, silicone has become the go-to elastomer for use in engineered products.

We regularly supply engineers, manufacturers, and inventors with tubing, cords, and bands, as well as more complex profile shapes or molded products from solid silicone and other elastomers. In addition to that, we also produce open-cell or closed-cell silicone foam.

Using the extrusion process, the finished product can be manufactured in continuous lengths or cut to length and packaged to meet the customer’s usage needs. Lastly, we can imprint your product information, logos, or graphics on the finished product.

Principle Of Extrusion Molding

First, the pretreated silicone raw material enters the extrusion machine, and under the action of high temperature and high pressure, it is output into a continuous silicone strip, whose shape is determined by the die and extruder head on the machine. After that, the silicone strip will be repeatedly Pulled and heated several times to achieve the purpose of curing.

Most customers are keen to use a silicone extruder to extrude silicone into regular-shaped silicone products in plates, tubes, or strips. The finished product produced by this method can be cut arbitrarily. Due to the difference in process and process shape, the application of extruded silicone products is mostly in the fields of medicine and food machinery.

Typical Properties Of Extruded Silicone

Biocompatibility

Silicone is non-toxic and non-allergenic, which makes it unlikely to cause negative reactions with human tissue when used in medical devices and equipment.

Resistances

As an inert material, silicone does not react with most chemicals or other materials. Silicone resists most bases, ultraviolet radiation, ozone, water, and oil. It also inhibits the development of molds and fungi.

Dielectric strength

Extruded silicone materials act as good electrical insulators and won’t degrade under typical exposure to current.

High-temperature resistance

Most common silicone extrusions can deal with temperatures as high as 500°F. Silicone extrusions are also flame retardants.

Elastic memory

Silicone extrusions feature excellent elastic memory, ensuring they will maintain or return to their original shape after exposure to high pressures or compressive forces.

Transparency

Extruded silicone’s relative clarity makes it easy to color or use in clear tubing.

At Jution Silicone, we pride ourselves on our ability to design custom silicone extrusion products to meet virtually any need. Our manufacturing processes adhere to many industry standards, such as FDA 26CFR, ISO 9001:2015, ASTM, ITAR, Buy American Act, WOSB, and MILSTD-105e. We can also develop unique formulations to meet specific application requirements.

Advantage:

  • Minimal lead time: Short set up a time
  • Easy to prototype: Minimal wastage
  • Widest range of part sizes: Perfect for the manufacturing of parts with a very large cross-section
  • Dimensional stability: Capacity to process stiff, high durometer materials, Excellent for low quantities of parts requiring a long cure time
  • Low tooling and equipment costs: Tooling is simpler and more cost-effective than injection molding, Although this technique has a longer cycle time, it is a low-pressure mold, which means it’s inexpensive to produce a variety of cavities without high tooling costs.
  • High production rates and shorter production cycles (results in lower per unit cost);
  • Allows for close tolerances in small intricate parts;
  • Requires little post-production work because parts have a finished look upon ejection;
  • Full automation is possible, which leads to reduced production costs
  • Design: Multi-colored. You can get 12 colors in one product without any printed.
  • Flexibility: Can make the 3D show with the products.
  • Attraction: More attractive and cute as gifts for the kids and Women

Design: Multi-Material. You can get 2 different material in one products

  • Extrusion molding also comes with its own set of advantages.
  • Continuous process can produce lengths of up to 60 feet;
  • Consistent cross-section results in the production of complex shapes;
  • High production volumes;
  • Low cost per pound of materials used;
  • Good for producing tube-shaped products such as pipes and hoses.
