When designing Medical Mould, various key factors must be comprehensively considered.

In the fierce competition of the current medical plastic mould manufacturing industry, mould and injection moulding processing costs are undoubtedly the focus of attention for businesses. In order to reduce costs and increase economic benefits while ensuring quality, mould manufacturers must carefully consider multiple key factors during the mould design process:

Medical Mould Design

  1. Injection Cost Consideration:
    Based on the size and price of the equipment, reasonably plan the product ranking method and number of cavities. The cost calculation for injection moulding is usually based on frequency, so the larger the number of moulds produced, the lower the injection cost.

  2. Product Shape Design:
    Accurately determine the parting line position based on the product shape standard. The design of the parting line should facilitate the processing, venting, and demoulding of medical plastic moulds. It is worth noting that the larger the product volume, the greater the potential issues with shape design.

  3. Gate Method Selection:
    Carefully design the shape, size, and vent position of the main and branch runner. Hot runner moulds have higher costs but save on gate expenses. The choice of gate method depends on the user's actual needs.

  4. Product Demoulding Strategy:
    Clarify the ejection method and ejector pin position, and arrange them reasonably. Generally, the larger the ejection position, the higher the mould cost.

Additionally, in mould design, consideration must also be given to product shrinkage and injection time to determine the cooling or heating method and arrange the position of the cooling channel. At the same time, to extend the service life of medical plastic moulds, the hardness, thickness, and size of the mould material must be selected reasonably. Finally, based on processing difficulty, the formed parts should be reasonably disassembled, and the wire cutting structure shape should be carefully designed.
