Mould Design

Compression molds are designed utilizing the latest CAD / CAM technology. Our engineering department uses UG 6.0 and ProE wildfire as well as SolidWorks and AutoCAD to service your needs. We specialize in SMC, BMC, GRP mould and molding processes. Compression mould sizes are customized to fit presses ranging up to 3000 ton clamp force, which can be steam, electric, oil and platen heated. Mould vacuum systems can be added to enhance the surface quality for cosmetic parts. The resin properties of thermoset molds include rigid part structure, dielectric properties and high temperature stability. Complete project management support is provided from prototyping, through mass production launch, and life cycle tracking for reliability and maintainability.

Smc Mould is usually designed with hydraulic cylinders with flow diverters for the ejection side. In order to keep all cylinders steady motion unanimously, we will add the equalization cylinder. Many of the tools are polished to diamond finish and textured prior to chrome plating. We hot fit the tool shear edges in our oil-heating machine or providing core cavity temperature differentials per customer specification prior to hard chrome plating. The core half of the tools usually have self siphoning bubblers for quick and uniform heat up to molding temperatures. The tools are either machined from high hard P-20, heat treated H-13, 1.2343or heat treated S-7úČ8407 to provide the longest life possible.

   Compression moulding
Layers of SMC or preformed pellets of BMC are placed into the heated tool. Through closing the tool the material fills the cavity and polymerizes. After complete cure the parts are released hot.With compression moulding highest mechanical strengths can be achieved.

   Transfer moulding
Preformed SMC or BMC is placed in the injection valve of the heated tool and is injected into the cavity after closing the tool. The material fills the cavities and polymerizes. After complete cure the parts are released hot. Transfer moulding is used for multi cavity tools of thick parts with high requirements for strength.

   Injection moulding
BMC or injection SMC are placed in the stuffer which feeds the injection unit. For these thermosets non return valves are used. The Composit is injected into the closed hot tool, fills the cavities and polymerizes. After complete cure the parts are released hot. Injection moulding is used for highest precision parts and complex geometries.

   Injection-compression moulding
BMC or injection SMC are placed in the stuffer which feeds the injection unit. For these thermosets non return valves are used. The Composit is injected into the semi closed hot tool, fills the cavities and polymerizes. After complete cure the parts are released hot. Injection compression preserves the fibres and improves the degassing of the cavities. The process is used for parts with high mechanical strengths.
