Several factors must be considered when deciding whether your part requires a large-ton machine. These factors include size, material, and safety considerations. Experts recommend adding a 10% safety factor to the clamping force calculation to accommodate potential defects. Key considerations to consider are part size and complexity, material type, projected annual volume, quality requirements, mold design, and seeking expert consultation.

Large-part injection molding, also known as large-tonnage injection molding, shares similarities with standard injection molding but requires higher-tonnage injection molding machines (500 tons or more) to manage the increased clamping force needed for larger surface areas. Understanding the differences helps in selecting the right equipment and processes.

We also work with our customers to devise inventory solutions to meet their unique needs for safety stock, and “just in time” delivery.

With the right equipment, technology and staff, we’re well-prepared to meet your demands and exceed your expectations—no matter how stringent they may be.

Over the years, we have invested heavily in our equipment and staff. This means is that we have ample capacity to complete a variety of projects. We have capability to mold items up to 8 pounds, as well as objects as light as .4 ounces. Our machinery and processes enable us to work to extremely tight tolerances, creating products which are consistent of the right dimensions.

These machines offer cost-effectiveness, space efficiency, energy efficiency, suitability for large mold sizes, and flexibility in mold configurations. They have a smaller footprint than three-platen machines, making them ideal for limited-space environments.

The two-platen injection molding machine is ideal for medium—and large-sized machines. It features a unique design with two platens holding the mold halves during injection. Unlike traditional three-platen machines, this design is compact and efficient, ensuring precision and efficiency in molding large plastic products.

Large-part injection molding finds extensive applications across various industries, offering unparalleled advantages in producing oversized plastic components.

Gas-assisted injection molding (GAIM) is a technique that uses an inert gas, typically nitrogen, to help with the injection molding process. In GAIM, the gas is injected through air holes in the mold or the nozzle of the injection machine into the molten plastic within the mold, creating hollow sections in the part. This assists in pushing the molten plastic into the mold cavities, ensuring uniform filling and reducing internal stresses. By incorporating gas-assisted injection molding into their processes, manufacturers can achieve higher efficiency, better product quality, and reduced production costs, making it a valuable technique in large-part injection molding.

Would you ever leave your valuables unprotected? Neither would we. Your molds are an investment in your company and critical to your business—we understand this. That’s why we store and protect our customers’ molds in a water and fire safe storage area.
