Choosing the right injection mold supplier is crucial for your manufacturing process. Whether you need complex designs, tight tolerances, or specialized materials, the right partner can help you get your product to market faster and ensure quality standards.
Evaluate how long the company has been in business. Years of experience suggest stability and reliability.
Know Your Needs
When you request a quote from an injection mold supplier, it is normal for the engineer to ask numerous questions about your part and the intended end product application. This ensures that their quotation will be customized to your specific needs. However, if you notice that the supplier asks few to no questions upfront, it is a sign that they do not have the capabilities to meet your project requirements.
The right injection molding partner will consider your part’s intended use in design, material selection, and production techniques. They should also have manufacturing capabilities such as process monitoring, scientific injection molding, and decoupled molding to achieve a high-quality final product.
Additionally, it would help if you looked for an injection molding company that offers a transparent and communicative mold-making process and can explain industry terms to you in a way that makes sense. This will help to ensure a seamless collaboration between you and your injection mold supplier.
Ask For References
From the start of your project, you want to ensure that the injection molding company you select has a track record of quality, on-time delivery, and manufacturing expertise. Ask for references and examples of completed projects that are similar to yours.
A good plastic injection molding supplier doesn’t just produce parts; they also provide valuable engineering and design services. For example, they may offer design for manufacturability (DFM) feedback, rapid prototyping, and guidance for material selection.
Switching injection mold suppliers is not something you want to do multiple times. Switching is costly and time-consuming because of the complexities of shipping the mold, qualifying components, aligning supply chains, and on-boarding vendors. To avoid this, look for an injection molding partner who offers precise quotes you can rely on for accurate financial planning. These quotes should be specific to your project and shouldn’t contain generic language like “10 cavity, class 101.” Ask for sources to ensure the provider is stable and has documented backup arrangements in case of unexpected events.
Visit The Plant
Visiting a plastic injection molding supplier’s plant is an essential step in the selection process. This allows you to see firsthand how the company operates and its level of customer service. It is also an excellent opportunity to assess whether the company has any issues or problems that may affect the production and delivery of your product.
Ask the supplier how they handle quality control and inspections. You want a partner dedicated to quality who will go above and beyond to ensure your project meets or exceeds your expectations.
Inquire about the supplier’s experience working with different plastic resins. Choosing an experienced company will help avoid potential production or quality issues.
Compare Quotes
Arm yourself with all the information you need to make an intelligent sourcing decision by requesting quotes that include every step and cost involved. This will help you to evaluate each potential molder’s risk levels and cost structure.
Evaluate the potential injection molding supplier’s capacity to meet your desired production volume requirements. This includes determining their injection molding machines, production capacity, and ability to meet your desired delivery timelines.
Look for an in-house injection molder that offers complete rapid prototyping capabilities, including wire EDM, CNC machining, chemical etching, and metal 3D printing. They can provide you with a better value for your money and shorten the time to market for your plastic parts. The right shop offers a variety of other services that you might need down the road, like injection molding and mold repair. This allows them to keep your costs low and manage your supply chain efficiently. This will save you time and money in the long run.
