Rotational Molding of a Plastic Shield Tank for the Ice Prevention Industry
Stern Industries, a company known for its quality services and cost-effective solutions, offers extensive expertise in rotomolding. We help customers in a variety of industries to take their products from concept to reality. An example of this was when we were commissioned by a material handling industry client for the rotational molding of this plastic tool case.
The case, was designed to be lightweight and easily carried by military personnel, and was created using a unique process. After the rotomolding process, spray foam insulation was used to enhance the durability of the case while maintaining a manageable carrying weight. The box measured 24 long x 17.40 wide x 10.150 high, with the lid measuring 22.23 long x 16.05 wide x 0.75 high, and a total weight of 14 lbs., it also met tolerances of ± 0.100. The case was made of linear low density polyethylene (LLDPE) and Ethafoam, and was finished with shot peen at 80 PSI.
Following completion of the cases, we performed various inspections to ensure the customers specifications were achieved, including the use-of fit, form, and function gauge inspections, as well as light inspection of voids in the foam. We current y manufacture over 400 of these cases for this customer annually. At Stern Industries, our goal is your satisfaction. Contact us today to learn about all of our capabilities.
