Custom Plastic Injection Molding: Your Questions Answered

If you’re considering utilizing our custom injection molding services, here are the answers to any question you might have about the process.
 
 

How do you know if injection molding is the right process for a product?

There are several ways to manufacture a plastic part. Understanding and knowing the part design, the end function of the part, the quantity needed, and the target part cost will help determine if injection molding is right for you. 

 

How long does it take to build a new mold?

Depending on the complexity of the part, the number of cavities, parts in the mold, and the size of the mold, it can take anywhere from 2 to 26 weeks to build a new mold.

 

Will the molds for my part be maintained between production runs?

Yes, all molds at Pioneer Plastics are on a PM (preventive maintenance) schedule.

The Advantages of Custom Injection Molding:

 
 

Plastic Parts Strength & Stability

The injection molding process offers numerous ways to ensure parts are strong and durable. Wall thickness, ribs (for support), and plastic resin selection are just a few mechanical characteristics that support product strength.

Thicker walls are more expensive due to longer plastic injection 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 much more durable than commodity-grade resins, which are typically used in consumer products like packaging.

 

Environmentally Friendliness

Products that are injection molded tend to last longer due to their quality and strength which reduces the number of molded parts that get thrown away over time.

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

 

Complex Machining Capabilities

A skilled tool and die craftsman uses lathes, mills, or CNC machining to create the plastic mold. A variety of sizes, colors, shapes, and finishes can be created with our injection molding machine.

Molding services like insert molding are used to inject resins over another material. An example of this is threaded fasteners that have metal in the center and a plastic shell. Overmolding is most commonly used to enhance the appearance or function of a 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.

 

Cost-Effectiveness

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 production without compromising quality or adding manufacturing costs. If you’ll be producing a large volume of your part in every run, injection molding will be a cost-effective option.

 

Flexibility in Design

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

Before the 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.
