Injection Molded Plastic Part Design Guidelines

Good part design can reduce tooling costs, improve part quality, shorten production cycles, and help prevent manufacturing issues. Below are some of the most important design considerations when developing parts for injection molding. 1. Maintain Uniform Wall Thickness Keeping wall thickness as consistent as possible helps plastic flow evenly through the mold and reduces the […]

Blow Molded Plastic Part Design Guidelines

Blow molding is commonly used to produce hollow plastic products such as bottles, containers, tanks, ducts, and housings. Designing parts specifically for the blow molding process helps improve part quality, reduce production costs, and achieve more consistent wall thickness. 1. Design for Uniform Wall Thickness Uniform wall thickness is one of the most important considerations […]

Thermoformed Plastic Part Design Guidelines

Good part design can improve material distribution, reduce tooling costs, improve part quality, and help ensure consistent production. Below are some of the most important design considerations when developing parts for thermoforming. 1. Select the Appropriate Mold Type (Male vs. Female) One of the first decisions in thermoforming is selecting whether a male or female […]

Rotational Molded Plastic Part Design Guidelines

Good part design can improve material distribution, reduce tooling costs, improve part performance, and support efficient production. Below are some of the most important design considerations when developing parts for rotational molding. 1. Maintain Uniform Wall Thickness Rotational molding naturally produces hollow parts, but large variations in wall thickness can affect cooling rates, dimensional stability, […]

Material Selection Guidelines for Plastic Manufacturing

Selecting the right material is one of the most important decisions in any plastic manufacturing project. Material selection affects product performance, durability, appearance, manufacturability, and overall cost. Whether a part is produced through injection molding, blow molding, thermoforming, rotational molding, or LSR molding, choosing the appropriate material early in the development process can help improve […]

Achievable Tolerances in Plastic Manufacturing

One of the most common questions during product development is, “How tight can the tolerances be?” The answer depends largely on the manufacturing process, part design, material selection, tooling, and production requirements. While all plastic manufacturing processes strive for consistency and repeatability, each process has its own capabilities and limitations when it comes to dimensional […]
