What issues should be noted in the design of rotational molding products?
1. Does the design include deeper side depressions in the direction of product detachment. If so, they need to be designed outside or as movable inserts, which will increase the cost of the rotational molding mold. Due to the collapsibility of plastic, some small depressions can be disregarded. However, it is important to understand how much depression level does not require additional molds.

2. How many mold blocks are there. Under standard conditions, there are two molds, but manufacturers of roll molded military boxes may require multiple molds if their product design is complex. This will endanger the cost of molds, maintenance of molds, and the cost of plastic parts.
3. The surface treatment required by the manufacturer of the military box for rotational molding of the product, whether it is cast on the surface of the mold or machined on the forged mold. In addition to storing oil in the hydraulic system, the rolling plastic military oil tank also plays a role in heat removal, separating bubbles in the oil, and settling residues. The difference in surface treatment level not only poses a great threat to the cost of the mold, but also sometimes special surface treatments can harm the product's mold production.
4. Is there an area on the product where there are two boundary layers where the resin flow rotational molding military box supplier cannot move well. How far is the distance in this area. If the distance is long, the surface treatment of the mold here will be difficult and increase the cost. If it is very narrow, the resin is difficult or even impossible to flow into the cavity.
5. Is the arc sufficient in the design to allow the resin to flow freely to every area of the mold. The roll molded military fuel tank must have sufficient capacity and consider the requirements of heat removal as much as possible. How much is a sufficient arc radius.
6. Whether to use inserts to adhere other components to plastic products. What are the parts of the inserts and whether they maintain their condition during the molding operation.
7. Where is the analysis surface of the mold. Sometimes the aesthetic of a product must differ from the specific requirements of mold making in terms of analytical difficulties.
8. If the compressive strength of the product wall is required to be high, should reinforcement plates or "kiss like" structures be designed on the product. Rotational molding water tanks are suitable for the production of various types and small batches of plastic products - because the mold used for rotational molding has a simple structure and low price, it is very convenient to change products.
