Plastic injection molding is a competitive market, which leaves businesses in need of plastic components with a number of options. However, when choosing a provider you want to partner with to optimize your part, supply, and costs, you need to take several considerations into account.

Although useful and informative, researching plastic injection molding companies near your area is no longer enough. You need to know exactly what to look for in a manufacturer to avoid common problems, including late deliveries, poor quality, capacity constraints, etc.

How to choose the best plastic injection molding company?

Manufacturing plastic parts and components through injection molding is a cost-efficient solution that can help businesses optimize their existing components and enhance their operations. However, for businesses from different industries to benefit from it, they first need to find a trusted partner that can meet their needs. 

Therefore, if you’re considering working with plastic injection molding manufacturers or changing your current provider, you need to consider these five most important criteria.

  1. Reliable production

    Your plastic injection molding company should be able to meet high industry production standards and deliver your product on time. They should employ a multistep process of project design and development and provide you with tangible proof that their manufacturing process can meet your needs.

    Additionally, their production process should be able to provide a consistent level of product quality every time. Feel free to ask a potential partner whether they are ISO-certified, as this is independent verification that they meet required industry quality standards.

  2. Timely project completion

    Look for a company that can deliver your parts and components within the agreed timeframe. The provider should maintain open communication with you and discuss your needs every step of the way. They should also be able to obtain the materials they need for the molding process and avoid delays.

    Therefore, it’s essential that your preferred provider has an efficient way of handling your project and managing their team. This will ensure on-time delivery and provide you with a great level of reliability.

  3. Engineering-based expertise

    Finding a partner that has an in-house team of experienced mold engineers is essential because they will be able to optimize your plastic components and produce them to your exact specifications. A provider with engineering capabilities will be able to produce plastic parts that can function smoothly in a specific application.

    Furthermore, experienced technicians can also help determine the specificities of your project and manage it from initial development to completion.

  4. Provider dependability

    Before hiring your plastic injection molding company, you should discuss some additional considerations. For instance, ask them about their experience in the industry and whether they can provide you with some client recommendations. Discussing their manufacturing capacity, ISO metrics, and delivery practices is also essential for determining whether they can fulfill your requirements.

  5. Science-backed, advanced practices

    Reliable plastic injection molding companies stay informed of the most recent advancements in plastic injection molding and implement proven design and production practices. Your potential provider should use science-backed techniques and tools that will provide long-term value and minimize possible failures or unnecessary costs.

    Scientific approach is necessary for not only producing high-quality plastic components, but also being able to repeat the process with a minimal level of deviation and maximum level of product consistency.

Frequently Asked Questions

What is plastic injection molding?

The method of plastic injection molding is used for manufacturing a wide range of plastic parts, components, and other products by heating the plastic until liquid and then placing it into a mold before cooling and solidifying it.

This type of manufacturing process is suitable for mass producing different items in large volumes, no matter their complexity or shape. What’s more, the method of plastic injection molds is very cost-effective, making injection molds the solution of choice across many different industries.

What are the steps of plastic injection molding?

Plastic injection molding consists of several steps. Once the plastic material reaches a high enough temperature and consistency, the manufacturing procedure can begin. The steps are as follows:

  • Clamping
  • Injection
  • Dwelling
  • Cooling
  • Opening of the mold
  • Product removal

What type of resin is used in injection molding?

There’s a wide range of materials to choose from for plastic injection molding, including:

  • Polyacetal
  • Acrylics
  • Rubber
  • Nylons
  • Polyolefins
  • ABS
  • Polycarbonate

Also, there are different combinations of these and other materials, as well as additives molders use to enhance certain properties of resins used by plastic injection mold manufacturers. To adequately choose the material, or resin, to use for your part, you need to pay attention to the following aspects:

  • Hardness
  • Flexibility
  • Weight
  • Associated costs for using a particular material material
  • Aesthetics of the resin you want to use
  • Thermal properties, such as temperature resistance
  • UV resistance
  • Viscosity
  • Melt profile and temperature

At what temperature is plastic moldable?

Generally, plastic melts and becomes moldable at temperatures between 300 and 800℉ when producing injection molded products. However, the exact temperature at which a resin becomes moldable when performing plastic injection molding services depends on the type of resin and its thermal properties.

What are the main parts of injection mold?

A machine for injection molding, both for single and multi cavity molds, is made of four principal components – the clamping unit, the barrel, the hopper, and the base. It also comprises smaller parts such as ejector pins, injection unit, nozzle, hydraulic unit, and split mold.

How does plastic injection molding work?

The process of custom plastic injection molding services as implemented by reputable companies features heating and injecting the molten plastic into a closed mold tool under pressure. The plastic then cools and solidifies inside the injection mold. Next, the mold opens to eject the part and release the injection molded plastics.

What are the five functions of injection mold?

Hiring respected experts in the custom plastic injection molding industry operating near your location has many benefits, including high efficiency, complex geometry and detailed features, enhanced strength, automation that saves manufacturing cost, and the ability to simultaneously use various types of materials during plastic molding services.
