Custom Plastic Injection Molding Services

The custom plastic injection molding process uses complex manufacturing methods, analytical tools, and molding technologies to produce custom plastic components and devices.  While custom injection molds allow businesses to create parts quickly, the complexity of the mold design, material selection, and manufacturing process can be a challenge to navigate. For access to a total-solution system, including product design, prototyping, custom mold design, and production, partner with us at Special Tool and Engineering. 

Custom Plastic Manufacturing Process 

Injection molding is a manufacturing technique that produces custom plastic parts by injecting pressurized molten plastic materials into a metal mold. The mold is cooled after the injection process, making the plastic a solid component. Here is how the custom plastic manufacturing process works: 

  • Our customers outline product specifications according to project requirements. Our experienced manufacturers can accommodate even complex, rigid project needs.
  • Our customer meets with us to outline project needs and discuss component specifications.
  • We will design a prototype that adheres to precise specifications for our customer to review.
  • The prototype and plastic injection mold undergo testing to ensure form and functionality.
  • After the design is perfected and required changes are made to the prototype, the production cycle begins. We monitors the production cycle to ensure conformity and functionality. 

While the manufacturing process may seem straightforward, it is complex and requires a great deal of experience and precision to complete. At Special Tool and Engineering, we have the personnel and the expertise necessary to complete a manufacturing process successfully, from design to the final production run. 

Custom Plastic Molds

Many customers require tools or components that meet exact specifications. Custom projects are highly complex and require a high degree of precision. Custom plastic injection molding relies on various scientific methods, analytical components, and molding technologies to produce a custom mold. Custom components must be identical in form and function and must meet customer specifications exactly. Our custom plastic molding process aims to create a part that matches customer specifications. 

At Special Tool and Engineering, we employ designers and engineers experienced in creating custom parts for various applications. Our team can produce molds in-house to ensure maximum productivity, from design to mold filling analysis, CNC machining, assembling, and final production. Our design and engineering consultations are thorough, ensuring we can produce the parts customers need without wasting money or time on inaccurate molds. 

As a manufacturing method, custom injection molding comes with a number of advantages, including its ability to serve a multitude of industry needs and applications. Injection molds can be customized to meet precise specifications, producing parts that can be used in virtually any application. Another benefit of injection molding is the highly efficient, reliable parts it can make. The molding process considers customer specifications and creates components that meet the most complicated requirements. 

Our Molding Approach 

Utilizing advanced injection molding machines, our goal is to provide our customers with a comprehensive custom plastic injection molding process that creates precise components. This process involves many individual steps, including: 

  • Mold flow analysis
  • Product and component design
  • Component development
  • Kitting and assembly

Special Tool and Engineering also provides quality control services during every step in the molding process.
