With our decades of injection molding expertise, Plastic Design International, Inc. frequently engages in a collaborative design process with our clients. By working together to define the product specifications and evaluate material choices, we optimize the product in terms of performance and manufacturability.
We produced the custom antenna housing highlighted here for use with a handheld radio. Through our joint endeavor with the client, we developed a process for injection molding the component, which featured dimensions of 13.875” in length x .720” in width, and with a wall thickness of 0.055”. Our talented mold designers overcame the challenge of building the tool so we could mold more than 10.0” of the internal diameter of 0.200” without any draft. To comply with the part’s surface finish requirements, we created the molds with a 0.003” deep chemically etched texture.
Constructed from aromatic polyester-base thermoplastic, chosen for its thermal and chemical stability, we molded the parts using our high-productivity vertical clamp injection molding machine, which allowed us to uphold close ±0.003” tolerances. We continue to manufacture this part for delivery to the customer within a one or two week turnaround, depending on order size.

Plastic Design International (PDI) produces custom handheld housing that is almost 14 inches long with wall thickness of 0.055 inch. Antenna is made of aromatic polyester-base thermoplastic. We (PDI) worked with customer throughout the design, development and material selection stage to ensure their design is moldable. One of the challenges that we had to overcome is to develop a process and build the mold so over 10 inches of the internal diameter of 0.200” can be molded without any draft! Each part is molded utilizing vertical clamp injection molding machine. Parts are molded with tolerances of ±0.003 inch.
