Building Molds for Plastic Parts

Mold Building is a fundamental building block to successful injection molding. If not done with careful consideration, you risk getting unsatisfactory results. Even the best effort using state of the art tool technology doesn’t result in an acceptable outcome. That’s why you need a company with not only the right injection mold making equipment, but the mold building expertise to get the job done right. We live with the results of our mold building for many years to come

Plastic Injection Mold Building Experts

HiTech Plastics and Molds is a custom injection plastic manufacturer focused on plastic injection molding and mold building. Our team gets involved from the ground up to help you create a molding solution that takes maximum advantage of our processes. We work with your tooling budget to create a custom mold that meets your design needs and are committed to delivering high-quality molds and products on schedule. Contact our sales team today to discuss your injection mold needs.

Our molding shop has a combined experience of over 30 years, and we have a strong network of engineers throughout the U.S. to assist us with challenging situations. Access to such a large pool of experts gives us the ability to handle projects other manufacturers won’t touch.

Plastic Injection Mold Building Processes: Quality-Driven & Cost-Effective

Successful plastic mold building often requires multiple iterations of part design and mold modification to reach a successful outcome. Our engineers review your 3-D drawings carefully for accuracy and correct any design issues before we start. This essential first step helps us determine what’s required to achieve molding success.

We also use computer simulations of the mold making process to identify unforeseen technical roadblocks to successful molding. Finding these issues right away reduces the number of iterations required to reach satisfactory part geometries, thereby reducing the time and cost of manufacturing your products. 

Injection Mold Building

Tooling support for custom plastic molding and mold building are carefully monitored and often finished ahead of schedule.

Injection Mold Building Technology

Technology and molding expertise ensure a successful plastic injection mold design. HiTech has a complete set of mold design and manufacturing capabilities, including 3D modeling, CAD, and CAM as well as CNC 3 axis machining, EDM, and CNC turning equipment, pantograph, optical comparators and Real-Time capable computer tracked production equipment.

Our injection mold making experts can create your custom plastic mold from a concept, CAD files, and/or rapid product prototype. The in-house design and injection mold making team uses a combination of SolidWorks, Auto CAD and professional design partners in enhancing your product design. Using SolidWorks Premium Software allows us to simulate the injection molding process before we build your mold. Once we finalize the design, you can request a rapid prototype using 3D printing to see how the injection molded part will look and feel.

Injection Mold Building Services

We focus on quality and collaborate with your company’s engineers through each stage of mold making, including:

• Injection Mold Building Plan
• Identifying the number of injection mold cavities
• Pinpointing injection mold and part cooling requirements

We also help determine if inserts, hot runner systems, or any other factors are needed to contribute to the success of your injection mold and part.

Plastic Injection Mold Building Classifications

Different classifications should be considered when building a mold. The classification categories designate the number of cycles the mold will repeat before “wear and tear” of the mold. The mold class selected depends on the number of parts manufactured per year. For example, a mold made for high volume production, multi- cavities, and a long product life expectation will be built to the highest classification.
