Plastic Injection Molding: Four Things Plastic Parts Manufacturers should Understand

2 min read

Injection mold tooling and part production can be challenging even for the most experienced manufacturers. Not all product designers have years of experience working with plastics or managing designs that require advanced consultation. When producing plastic projects, the ultimate goal is to come with an optimized mold for the kind plastic, desired cycle time, part geometry and finish, as well as productive volume.

In terms of plastic injection molding, there are things that product manufactures should know such as:

Pricing Factors

Many product manufacturers use injection molding when manufacturing plastic parts. This is because the method can be employed at a reasonable price and with the use of a variety of materials. The pricing of part manufacturing depends on mold and part price factors. In terms of mold pricing, things such as design strategy, mold size, offshore or onshore production are the variables to be considered. Also, pricing varies depending on the size and design of the part, cycle time, gate location, material selection, and part tolerance.

Important Terminology

Plastic injection molding is evolving with technological and resin science advances. A lot of essential decisions in terms of tool build, maintenance, materials, and production take place as part manufacturers and injection molders like fibertech communicate. Every part must strongly understand short-term and long-term expectations that must be shared in the design and development process. Although some industry keywords and phrases have an obvious meaning, both parties must understand the common terminology used throughout the project’s completion.

Design Consultation

When producing plastic parts, manufacturers must pick an experienced injection molder that offers design consultation. Designing a plastic part for manufacturability includes a lot of essential aspects that cover areas of part design, material selection, tooling, and production. First, manufacturers must build parts around functional needs which can be achieved by considering design intent or the end-use. Also, it is imperative to take into account fabrication and assembly steps elimination, weight reductions, structural component improvement, cost reduction, and quick delivery of product into the market.

Technology in Mold Flow Analysis

Plastic parts manufacturers must also pick a partner that offers the latest technology for analyzing mold flow to save money and time. They can use mold flow software to assess the design to ensure it produces the most consistent and highest quality parts from every tool cavity. It is important to create a virtual model of the mold using the known data and chosen material’s characteristics, allowing the software to predict the way the material flows into the mold and its cavities.
