Plastic One-time Knife Injection Moulding

Cutlery products are roughly classified into three types from the perspective of use: aviation cutlery, household cutlery, and military cutlery. From the appearance of the product, it can be divided into ordinary cutlery and folding cutlery. Different products are equipped with different cutlery on different occasions. For example, the plastic cutlery used in restaurants are all ordinary cutlery, and the cutlery used on some foods is generally folded, which does not take up space and is convenient for packaging. Different cutlery moulds have different processing techniques.

Cutlery's plastic material generally has two kinds of PP\PS. Different plastic materials have different choices of steel materials for moulds. Cutlery moulds generally choose steel materials such as H13, S136, 2344, 2316, and quenching materials. Because cutlery products are fast-moving consumer goods, the moulds are generally multi-cavity, and the mould shape is designed to be square or round. Use the point gate method. The hot runner adopts a full hot runner or semi-hot runner. If the mould is designed to be square, then a semi-hot runner can be used, and the mould is made into a built-in type. The cutlery mould processing technology includes high-speed precision carving, high-speed milling and so on. Ordinary cutlery moulds are generally two-part moulds, while folded cutlery moulds have more sliders on the basis of two-part moulds. Therefore, folding cutlery moulds are more difficult than ordinary cutlery moulds.
