Component Assembly

We offer a full component assembly, which includes printing, assembling, welding, gluing, packing, and collating our clients’ products to their specifications. We provide in-line assembly for your products, which creates high-component content turnkey packaged products that are ready for delivery.

Metal Pad Printing

PTR provides a variety of printing and decorating options to add your logo or image to your metal parts and products. Metal pad printing is a great finishing option for parts that have the following characteristics:
  • The part has raised or recessed or convex/concave areas
  • The decorating area is near vertical wall/obstruction
  • The image is multi-colored
  • The metal part has multiple areas to be printed (not on a single plane)

Hot Stamp Decoration

Hot stamping is a printing method that consists of transferring a metal foil onto the surface of an object.
Benefits of hot stamping:
  • High-quality production and the strong grip of decorations on any surface
  • Hot stamping adapts to plastic, glass, metal, and wood. It can also be completed on a coated product without damaging the coating.
  • Can be combined with other printing techniques, such as metal pad printing


Overmolding is a process where a single part is created using two or more different materials in combination. It is often utilized for common applications, such as toothbrushes and shaving razors. Manufacturers choose to overmold as a means to break up color, to provide a soft grip surface, and to add flexible areas to a rigid part.

Typical Overmolding Applications

  • Plastic Over Plastic
  • Rubber Over Plastic
  • Plastic Over Metal
  • Rubber Over Metal

Customized Packaging

Customized products require unique, customized packaging. That’s why we offer customized packaging as a part of our full line of finishing services. We can create packaging that is specific to your brand and specifications.

First Article Inspection

First Article Inspection, Initial Sample Inspection Report, or Production Part Approval Process helps to provide information that is essential for all companies in the manufacturing industry. Through First Article Inspection, we analyze your sample parts before they are sent to manufacturing. During this time, we check for defects in production and provide you with a complete review of all the parts’ characteristics. This provides your team with a comprehensive analysis to help ensure quality and to avoid making critical mistakes early on.
