Plastic parts production makes up more than one-quarter of all U.S. manufacturing. Plastics play an integral role in a range of industries, from aerospace and automotive to medical devices, construction, packaging, and consumer goods.
Not all injection molding services are the same. To get the highest quality parts, you need to identify the best injection molding company that uses the latest technologies and production processes.
This article explains what to look for in a plastics manufacturer. Keep reading to find out how to get the best components available for your project or industry.
Evaluate Material and Technical Capabilities
Having a clear picture of your unique parts requirements is the first step to identifying a quality producer. Using this information, evaluate whether the raw materials and the manufacturing process the company uses will let you achieve your objectives.
There are many different types of plastics used in injection molding. Common ones include:
- Acrylonitrile butadiene styrene
- Polypropylene
- Polyethylene
- Polycarbonate
- Polyamide (nylon)
- Polyethylene terephthalate
Each of these has distinct weights and hardness/flexibility levels. Some will be more durable and resistant to wear and abrasion than others.
The same holds for injection molding production methods. Standard injection molding is suitable for most parts, but for applications that require hollow interiors, blow or gas-assisted injection molding is ideal.
Insert molding allows the inset of preformed metal or plastic components into a part. Multi-shot and micro-injection molding are useful for extremely small, intricate, or complex parts. Make sure the company uses the best materials and has the production capabilities that are right for your project.
Assess Experience and Expertise
Beyond their capabilities, look at the company’s experience. Specifically, assess the level of knowledge and training of their technicians. Do they have a proven track record of making quality parts similar to the ones required for your project?
Custom molding kills and knowledge extends to every aspect of the design and production. Drill down on these attributes related to mold and part design, as well as finishing. If you need specific services–like trimming, bonding, or further assembly–make sure those are available.
Also, look at their competencies in light of the production volume you require. Determine if the company can make the number of parts you need with consistent quality.
Compare Pricing and Lead Times
A final step to finding the best injection molding company is to compare pricing. Be sure to calculate per-parts totals for design, materials, and manufacturing.
If there are additional services you require, make sure that is reflected in the quote. Take into account professionalism and responsiveness, which can be valuable attributes going forward.
Ensure the company can meet any deadlines you have for parts availability. However, like with pricing, balance this with the other qualities already talked about. In short, the best manufacturing partner will not sacrifice quality and consistency for production speed.
Find the Best Injection Molding Company for Your Project
Finding the best injection molding company can be difficult, but it is not impossible. The important thing is to ensure that the one you choose can meet your unique industry demands promptly and at a competitive price.
