2.5 To 3mm 300L Custom Rotational Molding High Hardness

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

Another consideration is in the draft angles. These are required to remove the piece from the mold. On the outside walls, a draft angle of 1° may work (assuming no rough surface or holes). On inside walls, such as the inside of a boat hull, a draft angle of 5° may be required. This is due to shrinkage and possible part warping.

Another consideration is of structural support ribs. While solid ribs may be desirable and achievable in injection molding and other processes, a hollow rib is the best solution in rotational molding. A solid rib may be achieved byinserting a finished piece in the mold, but this adds cost.

Rotational molding excels at producing hollow parts. However, care must be taken when this is done. When the depth of the recess is greater than the width there may be problems with even heating and cooling. Additionally, enough room must be left between the parallel walls to allow for the melt-flow to move properly throughout the mold. Otherwise webbing may occur. A desirable parallel wall scenario would have a gap at least three times the nominal wall thickness, with five times the nominal wall thickness being optimal. Sharp corners for parallel walls must also be considered. With angles of less than 45° bridging, webbing, and voids may occur.

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.
