Best injection molding company: how to choose?

Injection molding involves melting plastic and injecting it into a mold to create products such as furniture, bottle caps, and car parts. When choosing a company, consider quality, reputation, price, and delivery time. Quality is important for safety, reputation can be checked through references and credit reports, price should be compared through identical specifications, and delivery time should be considered with a written history. Choose a company that is a good partner and meets all of these criteria.

Injection molding works by melting beads of colored polystyrene, plastic or resin and then injecting the material into a mold. The process is commonly used to manufacture items, including plastic glassware and cutlery, outdoor furniture, bottle caps, and automobile parts. There are four main considerations when choosing an injection molding company: quality, reputation, price and delivery time. You may want to consider all four elements together, to make sure you choose the provider that best meets your needs.

Quality is important because a poorly formed piece can be not only unattractive, but also unstable. Weakness of products such as car parts, furniture or chemical containers increases the risk of injury and liability. An injection molding company should produce parts free of air bubbles and foreign materials. Consider requesting samples of previous designs along with the quote so you can compare quality across vendors.

An injection molding business should also have a good reputation with past customers as well as within the business community. Asking and checking a company’s previous customer references is a good way to find out if it consistently meets delivery dates, produces quality products, and provides good customer service. You can also request a business credit report to determine the creditworthiness of the business. A prospective salesperson with a habit of not paying suppliers may have deeper financial problems and may not be the right salesperson for you.

Realistically, price is always a major concern. A competitive bidding process is the best way to ensure you pay a fair amount for your product. To get the most accurate comparison, identical specifications should be provided for each vendor. You should also ask who the molds belong to. If you own the molds, you can change manufacturers in your next production without having to pay for the molds again.

A product that arrives too late may not be useful, so delivery time can be a critical factor when selecting a supplier. Material availability, your existing production schedule, and testing a custom color all contribute to your production timeline. It’s best to make sure you have a written history that includes deadlines for actions to be completed, such as approving samples. You may also want to know how much of the lead time is made up of waiting raw materials and ask if the prospective seller has a backup vendor.

Ultimately, you’ll want to choose an injection molding company that will be a good partner across the board. This means selecting a company that has an excellent manufacturing track record, produces quality goods, is financially stable, and offers fair pricing and on-time delivery. Spending more time on the initial vendor selection process will save time and headaches later.
