Brief Introduction to Wide-Mouth Milk Powder Lid Mold
I. Function and Structure
The wide-mouth milk powder lid mold is used for injection molding of wide-mouth lids for infant milk powder cans. The lids must feature properties such as leak-proof sealing, easy opening, and hygiene safety. The mold typically consists of cavities, cores, gating systems, cooling systems, ejection mechanisms, and guiding/positioning components, ensuring precise dimensions and a smooth, defect-free surface of the lid.
II. Mold Material
- Cavity and Core: Commonly use P20 pre-hardened plastic mold steel, which offers excellent polishing performance, machinability, and wear resistance, suitable for mass production.
- Guiding and Ejection Components: Adopt 45# Steel or S50C carbon structural steel. After quenching and tempering, they ensure strength and toughness.
III. Hardness after Treatment
- The hardness of P20 steel after pre-hardening is 28-32 HRC, eliminating the need for subsequent quenching and allowing direct use in processing and molding.
- The hardness of H13 Steel steel after quenching and tempering is 48-50 HRC, ensuring components are not easily deformed during long-term use.
IV. Key Requirements
The mold must undergo strict precision control (e.g., cavity dimension tolerance of ±0.02mm) and surface treatment (e.g., mirror polishing) to avoid defects like flash or shrinkage on the lid. Meanwhile, the cooling system must be uniform and efficient to shorten the molding cycle and ensure production stability.
Wide Mouth Cap Mould
The Wide Mouth Cap Mould features a precision-engineered design with a smooth, mirror-polished surface for consistent production quality. After the injection molding process, it creates caps that fit wide-mouth bottles with diameters ranging from 50mm to 200mm. These caps are perfect for sealing a variety of products such as dried fruits, nuts, biscuits, and fruit wines. With easy-to-use, secure closures, they ensure proper sealing for long-term storage and freshness. The design allows for efficient filling, classification, and cleaning, making the Wide Mouth Cap Mould an essential tool for high-capacity packaging and versatile applications across industries.
