How to Find the Right Company

If you are a corporate buyer or engineer and your responsibility is to source complex plastic or metal components, manage custom part orders, or find a highly reliable manufacturing partner for injection molding or CNC machining, finding a trustworthy custom injection molding company or CNC machining company might be more difficult than you expect. 

The Benefits of Having Clear Long Term Expectations

When you start your search for the right manufacturing partner you should start by creating a clear long term business model of what you will need from your custom part supplier on your current and future projects. The details of every manufacturing project can vary widely and should always drive good sourcing decisions. Just to name a few considerations, not all injection molding companies or CNC machining companies have the same capabilities for production batch sizes, complete in-house manufacturing, or in-house quality assurance with CMM inspections. If it’s your responsibility to source a supplier and have a trouble free product launch please consider the specifics to make a good decision.

Criteria for Choosing the Custom Part Manufacturer

To find the right custom plastic injection molding supplier, or custom CNC machining supplier, you’ll need to consider a few factors, including:

  • Industry Specific Knowledge: The company should possess a proven history of producing the type of components you are in need of and be well-versed with the demands of your specific industry or niche. Many industries have their own set of supply chain expectations on quality, project management, payment terms, or regulatory compliance, etc.
  • Technical Expertise: They should showcase adeptness in all facets of processing. Whether your parts need injection molding or CNC machining, there can be manufacturing feasibility concerns, specific tooling requirements, etc. In addition, your custom part supplier should have experience with the processing requirements of your selected plastic or metal raw materials.
  • Available Capacity: Manufacturing capacity is a key metric that a good custom part manufacturer will monitor and maintain balance with. Manufacturers with too much extra capacity might be financially stressed which can lead to inconsistent and unpredictable pricing or even non-performance of your orders. Injection molding and CNC machining companies without enough available capacity can become overwhelmed by new orders and cause unexpected delays with your parts shipments.
  • Quality Assurance: Look for companies with stringent quality control procedures in place, ensuring the production of high-quality parts. While you can look for ISO certifications, it’s best to ask the company about their existing quality control procedures and in-house inspection methods—ISO certification or not, reliable manufacturing companies should have a sound planning and quality assurance process.
  • In-House Capabilities: The company should be able to provide a full suite of services without out-sourcing. For plastic injection molded parts look for companies that offer in-house mold making so the quality of your tooling and parts are single sourced to the same supplier. Custom part suppliers should also have modern machinery and equipment, and in-house CMM inspections.

Before you source your project with any company, it’s always a good idea to get comfortable with the people you are about to working with. Custom manufacturing can present a lot of challenges and generally there are big differences between high quality well-run manufacturers and very low cost suppliers.
