There are a lot of things that go into making plastic parts. But the single biggest choice that will affect multiple categories of strength, price, flexibility, production speed, and even mold design during the project is the kind of plastic resin you pick for your production. It’s also a decision that needs to be made by the client, not the mold or part designer. All we can do is suggest plastics based on your needs. Today we’re here to provide you with some background on the four most popular thermoplastics and why they are so often used.

There are many manufacturers that can make parts for your product. While we’re of course partial to injection molding, regardless of the process and the company, there are some key things that any manufacturer should have. One of those is certification – certification in whatever process they use, quality control, material sourcing, etc. In this post we’ll look at the types and specific certifications and standards you should look for when working with a manufacturer.

Weld Line Defects in Plastic Injection Molding

Injection molding machine ejects the finished part.

Every manufacturing process can introduce different defects into the final product. The goal of every manufacturer is to have the machines, process, and quality assurance in place to reduce and even remove flaws from final parts and products. In this blog, we’re looking at one of the more common part defects that can come from injection molding: weld lines. Let’s go over what weld lines defects are, how they are caused, and what injection molding companies do to avoid them.

Plastic Injection Molding: How Manufacturers Check Part Quality

Dial set to high with the words "quality level" on them, representing quality management systems.

How important is part quality for your plastic injection molded products? Like with all manufacturing, the injection molding process can introduce defects to parts from the cosmetic to the critical. Assuring the quality of the part requires these defect parts located, troubleshot, and removed. The specific needs of the client and the standards for their industry means many different processes and best practices may be called on to meet standards and quality. Let’s review six of the standards, processes, and studies we perform during plastic injection molding parts manufacturing.

Every business needs to prototype and test their products before they go to market, but this is especially true for startup companies building their flagship products. Your first products can make or break your company and having prototypes, and injection molding for startups gives you the flexability to start early with short-runs and prototyping. Regardless of your revenue source, from venture capital to crowdsourcing, the sooner you can make physical copies of your product, the better.

Looking at the Hidden Cost of Overseas Plastic Injection

Shipping containers waiting for loading into cargo ships for overseas shipping from shipyard.

When it comes to manufacturing plastic injection molds overseas or domestically, we’re familiar with both sides. As mold designers, mold makers, and mold manufacturers, we work with clients at each stage – including taking a mold we’ve designed and working with them to have them manufactured overseas or domestically. This is also true for where parts are made. When you’re looking at having tools or parts made with overseas plastic injection, it’s important to look at all aspects – not just price points – to avoid hidden costs.
