Plastic injection molding is a manufacturing process used to produce large quantities of plastic parts with high precision and consistency. The process involves melting plastic pellets, also known as resin, then injecting the molten material into a mold under high pressure. After the melted resin is allowed to cool and harden in the mold, the custom plastic part is ejected then inspected.

Before you proceed with your inquiry for custom injection molding services, please consider the following to ensure this is the right fit for your needs:

We are committed to creating high quality custom plastic parts for our customers. Our molds are all on a preventive maintenance schedule to help prevent unplanned downtime and delays.

Turnaround time: Consider the lead time required by each potential manufacturer to ensure they can meet your production timeline.

When utilizing more than one material, the desirable characteristics from each of the materials can be realized – the rigidity of a thermoplastic or weight of a metal mass combined with the flexibility, sealing, or delicate features of an LSR.

In the overmolding process, a finished molded component or a metal or other substrate is placed within the LSR mold during the LSR molding process. Once introduced, the mold closes and the LSR is molded around or over the presented substrate or component, integrating the two.

Our Sales and Engineering teams have over 175 years of combined expertise in project management and plastic part manufacturing.

Quality: Ensure that the manufacturer has a reputation for delivering high-quality products that meet your specifications.

Determining if injection molding is the right process for a custom plastic part depends on several factors, including the size and complexity of the part, the required material properties, and the production volume needed.

Material properties: Injection molding works well with a wide range of thermoplastic materials, but not all materials are suitable for this process.

We use custom molding to create display cases for sports memorabilia, toy cars, collectibles, and other clear plastic containers.

Choosing the right custom plastic part manufacturer requires careful consideration of various factors. Here are a few key things to keep in mind:

Pricing: Compare pricing from different manufacturers to ensure you are getting a fair price for your custom plastic parts.

Our advanced molds and molding capabilities enable us to fulfill even the most complex design requirements — without sacrificing quality, durability or aesthetic appeal.

Lead time: The lead time for injection mold tooling can be longer than other manufacturing processes due to design and fabrication requirements.

The overmolding injection molding process is sometimes confused with or referred to as two-shot molding. Although similar because the finished component of both consist of a combination of two different materials or substrates, the manufacturing process and bonding is different. In the 2k molding process, the two materials are both chemically and physically integrated providing a superior bond compared to overmolding.

In the case of connectors, covers, valves, and others components that use a seal, when produced as a multi-material component the product’s performance is enhanced. A superior chemical bond is achieved, the seal fits perfectly, remains in-place and eliminates seal rollover or displacement that can occur with loose seals added during a secondary assembly process.

Multi-shot or multi-component injection molding is a collective term that refers to an injection molding process where two or more materials are molded in the same molding machine and within the same molding process. The result, an integrated molded component consisting of multiple materials and substrates.

In two shot molding, the LSR and thermoplastic parts are both molded and combined during the same molding cycle. The molds for the LSR and thermoplastic parts share the same platen in the molding machine. Typically the mold for the LSR parts is on the top and the thermoplastics mold is on the bottom.

Two-shot LSR injection molding involves molding an LSR material and a second polymer in the same molding process. The second material can be either a compatible thermoplastic material or a different grade of LSR (different durometer or pigment). The two materials are molded during the same process and combined to form one integrated two-material component. This process is a two-shot injection molding process.

For product designers, the use of multiple materials in a single component allows for greater design flexibility to achieve complex part designs, desirable product features, and enhanced product performance.

The cost of injection molds can range from $10,000 to over $100,000, depending on the size and complexity of the mold. If you only need a small quantity of custom plastic parts, say 1,000 pieces or less, investing in an injection mold may not be the most cost-effective solution for your manufacturing needs.

Bringing your production back to the United States through re-shoring provides you with greater control over your manufacturing process. Global events in recent times have made supply chains across the world unpredictable and unreliable.

Custom injection molding involves significant up-front costs, typically ranging from $10,000 to $250,000, influenced by the size and complexity of the mold. If your project involves producing 1,000 units or fewer, alternative manufacturing methods may be more cost-effective.

Two-shot injection molding is also called “2k molding” or co-injection molding. To successfully perform liquid silicone rubber two-shot molding, a specially designed co-injection molding machine is needed, and a mold builder and molder that are skilled and experienced in LSR processing to ensure accurate alignment and precision placement.

A trusted plastic part manufacturer such as Pioneer Plastics, has in house engineers that can take your concept from start to finish. We will help design the custom plastic part and produce a prototype before we build the mold and start production.

The time required to build a new mold for a custom plastic part can vary significantly based on factors such as the part’s complexity, the number of cavities and parts in the mold, as well as its size. Typically, this process can take anywhere from 2 to 26 weeks.

In 2k LSR injection molding, there are two types of molds used: transfer molds and rotary molds. Using a transfer molding process, after the thermoplastic parts are molded, the molded parts are robotically removed from the mold and transferred up to the LSR mold for completion.

Production volume: Injection molding is most cost-effective at high volumes due to the initial tooling costs required to create the mold. If you only need a small quantity of parts, another manufacturing process may be more appropriate.
