Ice cube plastic mold cover block mould

The production of plastic ice cubes usually involves the following steps: 1.  Design and mold making  : First of all, the mold of the plastic ice cube box needs to be made according to the design requirements. The mold is a key part of the injection molding process, and its shape and size will directly determine the appearance of the final product. 2.  Raw material preparation  : Use polypropylene (PP), polyethylene (PE) or other suitable thermoplastics as raw materials. These materials should have good low temperature properties to ensure that the ice will not deform or damage the box during the freezing process. 3.  Injection molding  : The prepared plastic particles are heated and melted, and injected into the pre-designed mold through the mold injection molding machine. When the plastic has cooled and solidified, what is taken out of the mold is the first embryo of the ice cube box. 4. Cooling and stripping  : After injection molding, the ice cube box needs to be cooled under specific conditions to ensure its structural stability. The embryo is then removed from the mold for further processing. 5.  Secondary processing  : This step may include cutting, trimming edges, removing flash edges, etc. For ice cube boxes with specific design needs, such as those with handles or specific patterns, they also need to be processed accordingly. 6.  Surface treatment  : In order to improve the beauty or protect the product, surface treatment may be required, such as spray painting, printing LOGO or special texture. 7.  Packaging and Quality control  : After the production is completed, the ice cube box needs to be packed and inspected for quality to ensure that it meets the standard. The packing method may include individual packing, box packing or box packing. 8. Transportation and distribution  : Finally, the packaged and quality-checked ice cubes are shipped through the logistics system to retailers or sold directly to consumers. Environmental protection and sustainability are also important considerations throughout the production process, so recyclable materials may be selected or measures taken to reduce waste and save energy in the production process.
