Up front, we focus on design for manufacturability (DFM), rapid prototyping, and tooling support to ensure parts and tooling are optimized for production. This includes selecting proper cavitation and designing in-mold automation to reduce or eliminate labor when possible, such as auto-unscrewing features and in-mold labeling, for example.

Aroplax also offers value-added post-molding services, including assembly, kitting, custom labeling, packaging, warehousing, and fulfillment programs for key customers.

What materials do you work with?

Aroplax processes a wide range of thermoplastics, including commodity and engineering grades, composites, and custom compounds.

We work with materials such as polyethylene, nylon, and glass- or additive-filled resins, along with other engineered materials based on application requirements.

Nylon
Polyethylene (PE)
Polycarbonate (PC)
Polypropylene (PP)
Filled materials (glass-filled, mineral-filled, etc.)
Other commodity-grade plastics and engineered resins
