  • The existing injection molder or company is no more meeting the desired quality requirements
  • You want to move the manufacturing from overseas to your country

Plastic Injection Molding Companies

For whatever reason you want to hire a molding company you must hire the right injection molding company for the process. In this guide, we will help you know how you can look for the best companies around. But before that, let’s have a quick look at what exactly ‘injection molding’ is.

What is Injection Molding?

Injection molding is a very common manufacturing process for plastic part fabrication. Manufacturers develop a broad range of products using injection molding. The products to be molded can vary immensely in their application, size, and complexity. The process of injection molding depends on the use of injection molding machines, mold, and raw plastic material.

Injection molding machines are used to melt plastic, and then the melted plastic is inserted into the mold. The melted plastic finally solidifies and cools in the mold. The produced plastic parts are used for different applications.

Injection Molding Application Areas

The most common applications include their use in the creation of plastic housings. These plastic housings are useful in different products, such as household appliances, automotive dashboards, power tools, and consumer electronics, etc.

The injection molding process is also useful in the production of many items of everyday use. These items may include toothbrushes and even small size plastic toys. There are also several medical devices, such as syringes and valves that are fabricated using injection molding technology.

Choosing the Right Plastic Injection Molding Company

Because you are not going to search for an injection molding company very often, so you must choose it very carefully. To help you choose the right company, here are the most important questions to ask the injection molder before hiring them:

  1. Machine Capabilities and Number of Injection Molding Presses Company Have

Before you hire an injection molding company, ask them about their machine capabilities. Also, ask how many injection molding presses the company has. Ideally, the company should have a huge number of presses that tells you that they can handle more and more projects during the given period. An injection molding machine is measured by its tonnage or pressure. A normal machine should run from 40 - 4000 tons. Large size machines are required to accommodate the larger molds.

However, not every single part will run effectively on the larger machines. Only the molder can recognize the best machine depending on the size and number of parts and also the material. You should make sure that the company has at least 100+ injection mold presses and their machine capacities should be up to 105, and the clamping force needs to be 45-720 tons.

  1. The Team

You should make sure that the company has a really strong and experienced team. All reliable plastic injection molding companies have an in-house tool and design building team comprising of highly professionals and experienced individuals. Their team must be familiar with the latest EDM machine tool equipment so that they can operate them professionally. Ask all such questions before you hire a particular company. This ensures that the process from product concept to its completion will be done with perfection.

  1. What about the Mold Guarantee?

This is a very important question that you must not forget to ask. A manufacturing team that has built your mold from the scratch should offer you the guarantees. They should always be ready to help if there is a need for slight adjustments to the mold or if slight repairs are needed. Typically, the high-quality tools built by top companies, Sz-Changhong, rarely need repairs too often.

  1. Customer Support

It is important to know that who is going to support your project and communicate with you. Ongoing communication is important so you should be aware of the managers who are in charge of your project for runs, etc. You will need to have someone from the company’s side who can regularly be in touch with you to tell you about the project status. Therefore, make sure that the company will provide you the top-quality customer support in a timely manner.

  1. Quality Standards

You also need to know the quality standards that the company follows. Make sure that the company is certified and the certification should be from a recognized auditing company. Therefore, ask the company for their certifications and quality standards they follow.

  1. Maintenance Support

A reliable and credible company should have a consistent and rigorous preventive maintenance plan for the molds used in fabrication in their facilities. So, ask the company whether or not they provide proper maintenance support.

  1. In-House Tooling Capabilities

Tooling is of utmost importance to ensure that cost and quality objectives are met. If the company is having in-house tooling capabilities, then it will offer many advantages including saving your money and time. So, this is another important question that you must ask the company that you are planning to hire.
