Reshoring Injection Molding Services: What You Need To Know

Want to bring your custom injection molding back to the United States? Read on to learn more about bringing your supply chain back to the US.

Questions to Ask:

Do I own the molds? Check your agreement with your supplier. If not, a new mold will need to be built or that mold purchased from an existing supplier.

Is it a mold or insert that is part of a MUD base? Understanding this helps the new molder know what to expect.

Are drawings and or part samples available? You must have these to get an accurate quote.

Is material and packaging known? Material and packaging requirements are a key part of understanding what it takes to get you a quality part.

Is the size of the mold known? Some molders can’t run certain sized molds. Don’t waste your time with a molder that can’t accommodate your needs.

Are you able to get enough supplies before moving the tools? Transfer time or time to build a new tool will leave you without a way to get parts. Planning for this is important.

Reasons to Reshore

Global events. Think Coronavirus. Companies that purchase materials from China or other foreign countries have no access to their needed supplies in times of crisis.  

Offshore manufacturers may not assist with design. Often, the design is the most critical aspect of the process. If the design needs to be modified at any point, it’s much easier to work with a domestic manufacturer to make adjustments. Communication barriers like differences in time zones, languages, and software systems often exist with offshore manufacturers. There are far fewer communication barriers with domestic manufacturers. 

Local manufacturers will keep your designs protected. Since trademarks are territorial, a U.S. trademark registration will not protect your design in a foreign country. Trademarks must be filed in each country where you want your design to be protected. If you need your design to be protected in multiple countries, the International Bureau of the World Property Intellectual Organization (WIPO) will allow you to file an international trademark application for up to 92 countries concurrently. Applying for international trademarks may add extra time and costs to the offshoring process, which are factors that you wouldn’t run into with domestic manufacturers.

The quality standards of overseas manufacturers may not be the same as local quality standards. American manufacturers are held to strict laws and regulations regarding safety and quality. In addition to safety and quality, full regulatory compliance in the U.S. includes the makeup of resins and colorants (whereas, in international countries, those may not be included in regulatory compliance). These laws, regulations, and standards ensure the safety of employees and the safety of the product itself, so the customer can be sure that the product isn’t toxic or dangerous. 

You won’t be able to guarantee that international manufacturers are following rigorous standards like those set by the International Organization for Standardization (ISO), because no company is required to adhere to ISO standards. These ISO standard certifications are set to drive waste and costs down while driving product quality up. If offshore manufacturers are not ISO certified, it can result in poorer quality of materials, operations, and overall products. 

Longer supply chains equal slower turnaround time. An increase in distance means an increase in shipping time, shipping costs, and production time (due to time zone and communication barriers). Further distances can also mean unreliable delivery times because it can take weeks or even months to travel the distance. Offshore manufacturers may also be harder to reach- communicably and physically. 

Cutting down on transit makes domestic manufacturing a much eco-friendlier option. Your company will produce a much smaller carbon footprint by eliminating ocean shipping. According to the International Council on Clean Transportation, ships are responsible for 3% of global CO2 and greenhouse gas emissions (which equates to approximately 1 billion tonnes per year). Reliance on other countries can be detrimental to your business when importing and exporting capabilities are halted in the face of tariffs, tolls, pandemics, and government partnerships (or lack thereof). Reshoring your manufacturing services will protect your business from being hurt by these global situations. 

What to Do When Reshoring

If you want to use your existing molds, you’ll need to pull them from your current supplier and ship them to your new supplier. You’ll also want to send them the CAD drawings for the product if you have them. In the case that you are unable to have your molds shipped to the U.S., your new supplier will be able to use your CAD drawings to create new molds. Keeping your existing molds and designs will eliminate the costs of creating new ones – which can often be the most costly part of the process

Advantages of Custom Injection Molding

Injection molding is one of the most versatile processes for creating a custom plastic part. There are many benefits to the process. 

Strength & Stability

The injection molding process offers numerous ways to ensure parts are strong and durable. Wall thickness, ribs (for support), and plastic material selection are just a few options.

Thicker walls are more expensive due to longer cycle times and more material but can provide a very durable part.

Ribs in key areas can give extra durability where needed and not have the cost issues of thicker walls.

Parts made from engineering-grade resins are able to withstand extreme temperatures, friction, and corrosion. This makes them more durable than commodity grade resins, which are typically used in consumer products like packaging. 

Environmentally Friendliness

Parts that are created using plastic molding tend to last longer due to their quality and strength which reduces the number of parts that get thrown away over time. 

The molding process doesn’t waste materials. When a broken or unusable part is produced, it can be remelted and reused. 

Complex Capabilities 

A variety of sizes, colors, shapes, and finishes can be created through custom injection molding

Techniques like insert molding are used to inject resin over another material. An example of this is threaded fasteners that have metal in the center and a plastic shell. Plastic overmolding is most commonly used to enhance the appearance or function of a molded part, like adding a softer layer of resin to the handle of a part. 

It can be used for assembly and decoration, as well. If pieces need to be labeled or decorated, in-mold labeling may be used. Connectivity techniques like heat staking and ultrasonic welding can be used to join two or more parts together.  


It is important to pick a partner that handles the entire process – from design to actual injection molding. This is much more cost-effective because the process is handled by one manufacturer from design to distribution. 

Injection molding can handle large scale manufacturing without compromising quality or adding costs to the manufacturing process. If you’ll be producing a large volume of your part in every run, plastic injection molding will be a cost-effective option. 

Flexibility in Design

All of the needs mentioned above can be solved with a good design. Pioneer Plastics has over 200 years of injection molding engineering experience in our design team – we know what makes a good part based on what your needs are. 

Before the injection mold is created, we can create a prototype of the part using our 3D-printer. This allows you to experiment with the product and make any necessary adjustments before the mold is built. 

Pioneer Plastics is a turnkey injection molder and produces everything in the United States – no international trade/shipping concerns. We are equipped to take your part from concept to consumer. Contact us today to get started on your custom part.
