What are the gateways in the design of rotational molding products?
1. Does the design include deeper side depressions in the direction of product slippage. If so, they need to be designed outside or as movable inserts, which will increase the cost of the mold. Due to the collapsibility of plastic, some small dents can be disregarded. However, it is necessary to understand the level of dents without the need for additional molds.
2. What is the number of mold pieces. Under standard conditions, there are two molds, but manufacturers of roll molded military boxes may specify several molds if their product design is complex. This will endanger the cost of molds, maintenance of molds, and the cost of plastic parts.
Rotational molding processing
3. The surface treatment of the product should be specified by the manufacturer of the roll molded military box, 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 roll molded military oil tank also plays a role in heat dissipation, separating bubbles and sediment from the hydraulic oil. The difference in surface treatment level not only poses a great threat to the cost of the mold, but also sometimes specific surface treatments can harm the product's mold production.
4. Is there an area where there are two boundary layers in the middle of the product where the resin flow rotational molding military box dealer is not very active. How long is the distance between this area. If the spacing 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 each area of the mold. The roll molded military fuel tank must have sufficient capacity and consider the regulations for heat dissipation as much as possible. What is the sufficient semicircle radius.
6. Whether to use inserts to adhere other components to plastic products. What are the parts of the inserts and whether they can maintain their condition during the forming operation.
7. Where is the analysis surface of the mold. Sometimes the aesthetic perception of a product must differ from the specific regulations for mold making in terms of analytical difficulties.
8. If the compressive strength of the product wall is specified to be high, should reinforcement plates or "kiss like" structures be designed on the product. Rotational plastic water tanks are suitable for the production of various types and small batches of plastic products - because the mold used for rotational forming has simple structure and low price, making it convenient to convert products.
