company news about Which production process is better for cooler box and insulated container, injection or rotational molding?

1. Because injection molding has an injection port, the molded product will have a small part that is not needed soon, and there will be a process to cut it off, but it can still be found if you observe carefully; the injection molding process of plastic parts mainly includes mold clamping-Filling-Pressure Keeping- Cooling- Demoulding and other 5 stages

2. The biggest feature of rotomolding products is that there are no seams and no injection ports. Low cost of rotomolding molds - For products of the same size, the cost of rotomolding molds is about 1/3 to 1/4 of the cost of blow molding and injection molds, which is suitable for molding large plastic products

3. Good edge strength of rotomolded products - rotomolding can achieve a thickness of more than 5 mm at the edge of the product, which completely solves the problem of thin edges of hollow products

4. Can accommodate various inserts of the Rotomolding mold

5. The shape of the rotomolded product can be very complex and the thickness can exceed 5 mm or more

6. Can produce fully enclosed products by Rotomolding mold

7. Rotomolding products can be filled with foam materials to achieve thermal insulation

Both injection and rotational molding are plastic molding methods, but if produce containers, containers with insulation and coolers are better choosing for rotational molding
