RM's first step with a new program is to assign our engineering department, which has strong mold making and design experience, to be the customer's right hand when developing new designs and new tooling. The design team will follow the program through final production approvals. RM's engineering group is deeply experienced and committed to the correct final molded product for you. This experience is the result of building the most challenging plastic products demanded by the Energy Storage, Automotive, Industrial, and Commercial industries.

The earlier you include RM's engineering in the development of your plastic product, the more sure you are of the product's eventual success in the market. Errors which pass through the design phase are ten times as costly as those in the manufacturing phase. Our ability to work with multiple design software programs allows for electronic file transfer to reduce product design time significantly.
