Plastic Parts Manufacturing 101: Everything You Need to Know

When a product requires plastic parts, you consider manufacturing them from a manufacturer. Plastic parts manufacturing does require expertise in many things, and only an experienced manufacturer can get it right. Each step of creating a plastic part, from designing to molding, is crucial to ensure the right fit and endurance. You strive for the final product’s quality to get it right. If you are new to this entire concept and want to get it right without wasting resources with multiple tries, here is everything you need to know about plastic parts manufacturing.

Plastic Parts Manufacturing Process

Plastic injection molding is the most popular method of manufacturing plastic parts. Plastics are made of many components. The most common are oxygen, hydrogen, chlorine, and nitrogen. Manufacturing customized plastic parts is a step-by-step process. One needs to follow each step for accuracy. Using plastic injection molding has made manufacturing plastic parts easier and more convenient. But you do need to acquire all the information before proceeding further.

Estimating the cost

Cost is a determining factor in every business decision. Before starting with the plastic parts manufacturing process or seeking a manufacturer for manufacturing your parts, you need to estimate the cost to create the prototype and the final product to see if it’s feasible. A manufacturer charges in two ways, fixed and hourly. By estimating the cost, you can seek out the most cost-effective method.  

Drafting a design 

This is the first and most crucial step of plastic parts manufacturing. You can hire a professional to design the parts with great detail. Start sketching the part’s design and remember to include every geometrical detail. It will then be converted into a 3D model, inviting many changes to achieve functionality and accuracy.

Understanding types of plastic

After the 3D model comes the next step of choosing a plastic resin for manufacturing the part. Plastic resins differ in hardness, flexibility, and durability. They also vary in costs, so balancing the requirement with the associated costs is important.

Deciding on the plastic molding process

A plastic part manufacturer has various plastic methods, and plastic injection molding is the most sought-after technique, as it delivers the best results. Choosing the right process depends on the design and applicability of the product. Plus, the number of plastic parts needed and the available time for manufacturing are also important factors for deciding the right plastic molding process.

Building a prototype

This step might not be necessary, but it is highly recommended. Building a prototype precisely like the final product helps you determine the required changes and test out the functionality of the part. It is important to find flaws before proceeding with bulk manufacturing of the part. It is often easier to check out faults in a 3D model once the final product is the final product. By checking the prototype, you can fix the issues that may not be apparent initially. The plastic part manufacturer will have access to various prototype machines to help you with the same.
