Steel selection for compression moulds is an important engineering consideration because the mould is subjected to repeated mechanical pressure, friction, heating and cooling cycles, and wear during production. The correct steel must provide a suitable combination of strength, hardness, toughness, wear resistance, dimensional stability, corrosion resistance, machinability, and heat-treatment capability. For candle manufacturing, compression moulds […]

Mould cavity and core design is an important part of candle manufacturing, particularly when producing candles with specific shapes, dimensions, textures, holes, or decorative features. A properly designed mould ensures that the molten wax can be filled easily, cooled uniformly, and removed without damaging the finished candle. 1. Mould Cavity The mould cavity is the

Vacuum channels are passages incorporated into thermoforming moulds to remove trapped air between the heated plastic sheet and the mould surface during the forming process. They are an important part of vacuum-forming mould design because they allow atmospheric pressure to push the plastic sheet accurately against the mould. A properly designed vacuum-channel system helps achieve

Compression mould materials are selected according to the moulding material, operating temperature, moulding pressure, production volume, required dimensional accuracy, surface finish, and expected tool life. The mould material must withstand repeated heating and cooling cycles, mechanical pressure, wear, and chemical interaction with the moulding compound. A properly selected mould material provides good dimensional stability, reliable

Designing an injection mould involves developing a tool that can consistently produce high-quality plastic components with accurate dimensions, efficient cycle times, and reliable mould life. A well-designed injection mould must account for the part geometry, plastic material, filling behaviour, cooling, shrinkage, ejection, and manufacturing requirements. The mould design process generally begins with a detailed evaluation

Vent hole design is an essential part of thermoforming mould development, particularly in vacuum and pressure thermoforming. Vent holes allow trapped air between the heated plastic sheet and the mould surface to escape, enabling the sheet to conform accurately to the mould geometry. Properly designed venting helps achieve complete forming, accurate reproduction of fine details,

Choosing the right compression mould is an important step in achieving consistent product quality, efficient production, controlled material usage, and reliable mould performance. The appropriate mould type depends on the material being processed, component geometry, dimensional requirements, production volume, and the desired level of flash control. Compression moulds are commonly used for thermoset plastics, rubber,

Injection mould design is the process of developing a moulding tool that can reliably produce plastic components with the required geometry, dimensional accuracy, surface finish, and production efficiency. A well-designed injection mould must account for the part design, plastic material, injection process, cooling requirements, ejection, moulding machine, and expected production volume. An injection mould generally

Undercuts in thermoforming moulds are features that prevent a formed plastic component from being removed directly from a conventional mould along the normal direction of mould opening. They may occur as recesses, projections, hooks, grooves, or other geometrical features that lock the formed part onto the mould. Undercuts can provide useful functional features in thermoformed

Semi-positive compression moulds are a type of compression moulding tool that combines features of positive and flash-type compression moulds. They use a relatively close-fitting punch and cavity to control the flow of moulding material while still allowing a limited amount of excess material to escape through a controlled clearance or flash area. During the moulding
