Six Factors to Consider when Choosing a Resin to Produce Plastic Parts

2 min read

Production of a plastic part or product starts by determining the type of resin to use. The resin is the plastic product’s base which is the most important element of the final product that affects the cost, production time, life cycle, and usage. Choosing a resin is part of the design that must be done in the earliest stage of the process.

When choosing a resin, below are some things plastic injection molding companies like Fibertech take into account:

Part Price

An acceptable price for parts is determined by analyzing and understanding the economy and the market in which the plastic product will exist. It is necessary to justify the part price with current market resin prices to determine the product’s final makeup.

Part Requirements

Whatever is physically asked of the final product will be taken into consideration. A reliable company makes a broad array of plastic products or components that have a unique set of considerations such as the purpose and lifecycle of the part, price point, aesthetics, and environment in which the part will exist.

Part Design

The design stage of the part also involves resin considerations as the manufacturer determines the look of the product and how it will be molded. Raw plastics produce different results that will affect wall thickness, ribs and gussets, parting line and ejection, bosses, appearance parts, corners, fillets, radii, as well as holes and depressions.

Product Performance

Each product needs to fulfill its purposes. Part requirements and design attributes must be compared against the attributes of tried and tested plastics. Whether you want your plastic part or product to be disposable or recyclable, your plastic product manufacturer must identify the resin that falls within your product’s performance parameters.

Considerations During the Processing of the Product

Many plastic products require two different kinds of materials. In overmolding, plastic is molded with another substance to create a cohesive and useful product. In this case, the manufacturer will pick a resin that has a strong chemical bond with the substrate and understand both of the materials’ melt temperatures.

Availability of Materials

A plastic part manufacturer should take into account your product’s needs and put their experience with their materials to good use. Also, they will consider the supply and demand for plastic, especially if you need continuous production of your product. They will always have backup materials in case they might need it.
