The thin-walled meal boxes for take-out packaging are very popular, and they are also indispensable products in life. The demand for one-time packaging meal boxes is very large, and the packaging box mold market has also caught up with the development trend.
Disposable lunch boxes have low single-piece profit, so they need to rely on quantity to fight the market. This requires that it must be high-speed and efficient to produce. The lunch box mold needs to be produced by a high-speed injection molding machine. Under the high-pressure, high-speed injection of the high-speed machine, The mold needs to withstand high pressure, so high-hardness mold steel is needed to make the mold. The following DEYING mold is based on our manufacturing experience to briefly share how to correctly choose the thin-walled lunch box mold steel?
The mold steels for disposable lunch boxes we usually choose are DIN1.2316, DIN1.2344, DIN1.2738, S136, H13 and other pre-hardened mold steels. The selection of these hard steels can prevent the mold from deforming under high pressure injection and prevent the product from flashing. And other defects. Among them, S136 stainless steel is the first choice for customers, and it is also the most popular and most used.
Let's talk about the advantages of one of the commonly used mold steels, S136 mold steel:
1-S136 die steel is stainless steel, which guarantees food safety.
2-Stainless steel molds are not easy to rust, which is convenient for customers to maintain. Since the profit of the ultra-thin box is generally relatively low, if it rusts, it means that the mold needs to be re-polished, which will increase the weight of the product and reduce the customer's profit.
The polishing performance of 3-S136 is better, and the transparency is better if it is made of transparent products. Finally, S136 is a quenched mold steel, which is not easy to deform. Generally, ultra-thin box customers use high-speed injection molding machines to produce under high pressure. If the hardness of the mold steel is not hard enough, the mold is easily deformed and eccentric.
The knowledge about the selection of thin-walled lunch box mold steel is shared here. If you need high-quality disposable packaging box molds, you are welcome to contact DEYING.
