Steel 400L Rotational Molding Mold Oxidation Resistance

Four hundred liters of forklift bucket mold for making plastic products.

The rotational molding process consists of four distinct phases:

• Loading a measured quantity of polymer (usually in powder form) into the mold.
• Heating the mold in an oven while it rotates, until all the polymer has melted and adhered to the mold wall. The hollow part should be rotated through two or more axes, rotating at different speeds, in order to avoid the accumulation of polymer powder. The length of time the mold spends in the oven is critical: too long and the polymer will degrade, reducing impact strength. If the mold spends too little time in the oven, the polymer melt may be incomplete. The polymer grains will not have time to fully melt and coalesce on the mold wall, resulting in large bubbles in the polymer. This impairs the mechanical properties of the finished product.
• Cooling the mold, usually by fan. This stage of the cycle can be quite lengthy. The polymer must be cooled so that it solidifies and can be handled safely by the operator. This typically takes tens of minutes. The part will shrink on cooling, coming away from the mold, and facilitating easy removal of the part. The cooling rate must be kept within a certain range. Very rapid cooling (for example, water spray) would result in cooling and shrinking at an uncontrolled rate, producing a warped part.
• Removal of the part.

The plastic forklift bucket is light in weight, convenient to handle, large in capacity, and convenient to clean.

The rotomolding mold has no hot runner, cooling groove, etc., and the structure is relatively simple; the product molding process is pressureless molding, so the mold wall thickness is relatively thin and the structure is simple.

Rotomolding products have good one-time molding integrity, relatively high material utilization rate, no welding, and no leakage.

Mold production time and manufacturing costs are relatively small, and maintenance and repair are relatively easy. Molds of different sizes and different tonnages can be customized according to requirements.

Plastic products have strong impact resistance, high tensile strength, good oxidation resistance and aging resistance. Compared with traditional anti-corrosion storage tanks, it is inexpensive and cost-effective; plastic has the characteristics of internal and external corrosion and can be placed in a strong corrosive environment; and has excellent chemical resistance, can withstand most substance solutions, except for a few that can make it Swelling solution.
