Technical Characteristics of a Silicone Rubber Moulding Press

Firstly, there are different types of silicone rubber moulding presses available on the market, including compression moulding, transfer moulding, and injection moulding. Compression moulding involves placing a preformed rubber compound into a heated mould and applying pressure to create the desired shape. Transfer moulding uses a plunger to transfer the rubber compound from a chamber to the mould. Injection moulding uses a screw to inject the rubber compound into a heated mould.

The presses are made up of several components, including the hydraulic system, heating system, control system, and moulding system. The hydraulic system is responsible for providing the force required to compress the rubber compound into the desired shape. The heating system is used to raise the temperature of the material to facilitate the moulding process. The control system monitors and regulates the temperature, pressure, and other parameters to ensure consistent and accurate production. The moulding system consists of the mould and other components necessary for shaping the material.

In terms of specifications, the pressing force of silicone rubber moulding presses can range from a few hundred kilonewtons to several thousand kilonewtons. The temperature range can vary depending on the type of silicone rubber compound being used but typically falls between 150°C to 200°C. The cycle time of the machine is also an important consideration as it determines the production rate. Some presses have a cycle time of a few minutes, while others can take up to an hour.

Finally, it’s worth noting that silicone rubber moulding presses require regular maintenance to ensure optimal performance and longevity. This includes cleaning and inspecting the machine regularly, replacing worn or damaged parts, and keeping the hydraulic system properly lubricated.

What is a Silicone Rubber Moulding Press?

A silicone rubber molding press is a type of hydraulic press used for molding and shaping silicone rubber into various products. These machines are used in a variety of industries, including automotive, aerospace, medical, and consumer goods.

The silicone rubber molding process involves the use of high-quality silicone rubber material and the application of heat and pressure to shape the material into a specific form. The process typically involves the following steps:

Material Preparation: The silicone rubber material is mixed with a catalyst and other additives to prepare it for the molding process.

Compression: The press applies heat and pressure to the material, compressing it into the desired shape.
Cooling: The molded product is allowed to cool and harden, taking on the shape of the mold.
Ejection: The mold is opened, and the final product is removed.

Silicone rubber molding presses can be customized to meet specific requirements, such as different mold sizes and shapes and different levels of compression force. These presses can also be automated for increased efficiency and consistency in the molding process.

In addition to silicone rubber, other materials that can be molded using hydraulic presses include natural rubber, synthetic rubber, plastic, and metal. The type of press used will depend on the material being molded and the desired final product.

Liquid silicone rubber (LSR) is an elastomer molded into critical performance components for applications in medical, power, consumer, automotive, and aerospace applications. This article reviews process behavior, material modeling, and simulation of the (LSR) injection molding process. Each phase of the LSR injection molding process is discussed, including resin handling, plasticization, injection, pack and hold, and curing; and factors affecting the molding process are reviewed.

The processing behavior of LSR is marked by transient interactions between curing, shear rate, temperature, pressure, and tooling. Therefore, current LSR models for curing, viscosity, pressure, and temperature are discussed. Process dynamics and material modeling are combined in LSR injection molding simulations with applications in mold design, troubleshooting process-induced defects, and management of shear stress and nonuniform temperatures between LSR and substrates during over-molding.

Finally, case studies using commercial simulation software are presented, which have shown cavity pressure and flow front advancement within 3% of experimental values. Optimization of LSR materials, data collection, model fitting, venting, and bonding remain areas of continued interest.

In liquid injection molding (LIM), the LSR is fed to the relatively cool barrel of an injection molding machine and forced into a heated mold where it is cured. Molds employ hot and cold runner systems. In hot runner systems the entire runner cures and is removed with the
part, whereas a cold runner system keeps the LSR material chilled to prevent curing of the runner. In the latter configuration, the part does not have runner waste.

As illustrated in Figure 3, LSR typically is fed to an injection molding machine by pumping LSR parts A and B and any additives, such as color, from a bucket or drum, through a static mixer, and into the feed port of the barrel. Pneumatic or servo-driven pistons push a wiper plate into the component buckets.

The displacement forces the LSR and additives into the leader lines feeding into the static mixer in production LSR molding. Some systems incorporate flow measurement, bucket position, and pressure regulators to improve stability and increased accuracy. The mixing ratio for parts A and B is often allowed to vary up to 5% off ratio for a 1:1 ratio LSR without significantly impacting the process or final product properties.

Color typically is pumped through a third stream feeder line to the static mixer at a concentration ranging between 0.3 and 6.0 wt%.[17,61,62] Some commercial products are using additives at levels well above 5 wt%. The literature is limited with respect to static mixers and other production mixing methods.

Lopez et al reported using static mixers with as few as 13 elements, but more elements have been recommended for general use. LSR experiences some additional mixing during screw recovery.

Static mixers with 20 elements were suggested for LSR pumped into an injection machine that utilizes a screw compared to mixers with 32 elements that were recommended for plunger injection machines. Mixing elements have been reported using flow division or alternatively radial mixing. When the mixed LSR exiting the static mixer enters the feed port of the injection barrel, the pressure target at the feed port is about 0.55 MPa.

The technology for liquid silicone processing

In its original state, liquid silicone consists of liquid and transparent silicone in equal quantities. Silicone component A contains an
additional platinum catalyzer, the silicone component B is a cross-linking agent. Normally fillers for reinforcement, such as silicic acid or
quartz, are added to both components as well.

Both material components are delivered in 20-liter or 200-liter metal drums. These are connected with a metering system, and the lids
of the drums are subsequently replaced by the disk pistons of the material loading devices coupled with hydraulic or electric feed units. When the pistons advance, they apply pressure to the contents of the drum. Both material components are fed into a static mixer through tube connections simultaneously and in equal quantities. The mixing process starts the additive cross-linking reaction. In the mixer, colorants and/or other additives can be blended into the transparent silicone as well.

From the mixing block, the activated material blend is conveyed under pressure through a tube connected to the feed zone of the injection
molding machine’s LSR barrel. The barrel is cooled to between 20 and 25 °C by liquid circuit zones, to slow down the cross-linking process. As soon as a set volume of the reactive blend has been dosed, it is injected into a mold heated up to between 170 and 220 °C. Accelerated by the heat input, the completion of LSR cross-linking takes no more than a few seconds.

Control of the dosing and mixing system is synchronized via an interface with the injection molding machine.
