Silicone Parts Manufacturer

Silicone Parts Manufacturer

Silicone Parts Manufacturer

Invented in 1901, silicone resists radiation, oxygen, and other harsh chemicals. Medical-grade silicone is also biocompatible and ozone-resistant.

Custom manufacturer of injection/compression molded silicone rubber & foam and extruded products. Services include design, engineering, assembly, lathe cutting and splicing. Also offers prototype, low-volume production runs. Serves aerospace, telecommunication, military, medical and high technology industries.

Custom Molding

The ability to mold a silicone part to a precise geometry translates to a number of benefits, including the elimination of assembly and other labor-intensive steps. Silicone rubber parts can also be molded in large volumes, allowing companies to provide their customers with a more affordable product.

Liquid injection molding services for silicone, thermoplastic and two-shot molded components used in medical, automotive, consumer products and government safety and security industries. Cleanroom manufacturing, product development and in-house tooling construction services also offered. ISO 9001:2008 and ISO 13485:2012 certified. ITAR registered.

Custom manufacturer of compression, micro, flashless and liquid silicone rubber (LSR) injection molded products up to 24 in. in size, along with transfer and overmolding services. Capable of molding materials such as Viton(r), nitrile, fluorosilicone, EPDM, isoprene, styrene-butadiene rubber (SBR), FKM and polyurethane. Serves aerospace, biomedical, automotive, construction, chemical processing, electronics, fluid power and marine industries.

A silicone elastomer that maintains its shape over time and under stress, this non-latex Silicone Parts Manufacturer material is ozone-, UV- and heat-resistant. It is often used to make gaskets, seals, diaphragms and bellows due to its durability and flexibility. The company makes a variety of custom molded and extruded silicone rubber products, such as hoses, tubing, profiles, grommets, frames, O-rings and other parts. They are available in various colors and durometers, as well as in sheet form.

Extrusion

Custom manufacturer of standard & customized extruded & molded silicone products including O-rings, bellows, seals, bushings, pads & grommets. Fabrication services include CAD, wire EDM, coating & jacketing, inline punching & printing. ISO 9001 certified. Offers calendering, molding, injection, transfer & compression molding, and is capable of low to high volume production runs. Serves industrial, military & commercial industries.

During the extrusion process, solid silicone rubber is forced through a die of the desired cross-sectional shape. This process is typically used to make hoses, cords and complex profiles that have long, thin, and multi-layered sections. It is also used to make tubing, solid rods and profile gaskets that can withstand harsh environments such as extreme temperatures, chemicals, ozone, oil and UV light.

The advantage of this process over injection or compression molding is that silicone is naturally clear and transparent. This allows it to be color-coded easily for applications that require organizational or aesthetic considerations. Furthermore, extruded parts are more flexible and can be fabricated into complex shapes that would be impractical to manufacture using other processes. The company offers cleanroom molded silicone rubber products in Viton, neoprene, perfluoroelastomer and styrene butadiene rubber (SBR). Production capabilities include injection, compression, transfer and micro molding. The company is capable of producing prototypes and low to high volume production runs.

Liquid Injection Molding (LIM)

LIM is the process of injecting liquid silicone rubber into a mold. The process is used to produce products that would otherwise be difficult to make using HTV or high-consistency rubber (HCR) because of their special design requirements. Examples include medical-grade silicone pacifiers and duckbill valves, as well as other medical accessories that need to meet strict transparency standards for patient safety.

The first step in the process involves creating an aluminum casting that will be poured with the hot silicone mixture. The casting is then given a surface coating to protect it from abrasions and to add a desired shine or color. After the mold is prepared, a metering unit pumps two primary liquid materials, the base and catalyst, into a mixer Silicone Supplies where they are mixed until homogenous. A nozzle is then used to deposition the mixture into the designated mold.

LIM can be an extremely effective manufacturing method when paired with the right materials. Silicone is a great choice for this type of molding because it is durable and flexible. It is also able to resist high temperatures, making it ideal for parts that will be under the hood of vehicles or near engine components. Additionally, it is a fire retardant and won’t melt when exposed to high levels of heat. Lastly, it has excellent tensile strength and can withstand abrasions and extreme weather conditions.

Compression Molding

Silicone parts manufacturers offer compression molding services for producing complex shapes and large-sized components. A preheated, fiber-reinforced silicone or other thermoset material is placed into a heated mold cavity and closed at a programmed speed and temperature. Under these conditions, the material undergoes an irreversible chemical cross-linking reaction that results in a cured part. After cooling, the mold is opened and the molded part is removed.

Compression molding typically produces a quality product with excellent dimensional precision, temperature resistance and surface quality. However, the process is not without its challenges. Depending on the material being used, the type of mold and the pressure applied, defects such as flash, voids or porosity, uneven curing and delamination may occur. These problems can be minimized through careful mold design, accurate temperatures and pressure control and the selection of the right material for the job.

Using an incredibly precise Shore scale durometer, we are able to measure the softness or hardness of liquid silicone rubber (LSR). We use this information to ensure our molded products meet your exact specifications, which is especially important for items like seals and gaskets that need to have high levels of strength and durability. We also have the ability to overmold your LSR molded component with other materials, such as plastic or metal, which allows us to create composite products with unique properties that can’t be achieved with any other manufacturing technology.
