Our skilled and experienced technicians provide professional support for projects of all sizes and complexities, ensuring quality throughout.

Injection Molding Tool Lead Time ​

The time required to make an injection mold tool depends on the complexity of the design and the material used. A simple shape, such as a basic square made from softer steel like P20, can be completed in under one week. Harder steels take longer to machine and heat treat, while more complex shapes or advanced surface textures may need three weeks or more to prepare.

Advantages of Injection Molding ​

Once a tool is made, plastic injection molding is the fastest and most cost-effective way of manufacturing hundreds of thousands of finished plastic parts. Molded parts have excellent surface finishes with reliable and repeatable dimensional tolerances. And there are resins available to suit most common applications.

Process of Plastic Injection Molding ​

Plastic injection molding is a manufacturing method that involves filling a mold with liquid plastic resin under high pressure. The mold can have one or many cavities, allowing for the production of numerous parts. Once the mold has been carefully designed and built, the process follows these basic steps:

Material Preparation: The process starts with raw plastic resin in pellet form. These pellets are dried to the right moisture level, and if needed, mixed with pigments or colorants to get the desired color for the final product.

Feeding: The molding machine's hopper is filled with dried pellets. A reciprocating screw inside the barrel heats and moves these pellets toward the mold.

Melting: Inside the barrel, the pellets are mixed and heated until they melt completely, forming a liquid resin.

Injection: After the heated mold automatically closes, liquid resin under high pressure is fed into the mold cavity through a gate.

Cooling: The mold is then cooled for a short time to solidify the part inside.

Ejection: Finally, the mold opens, and the finished part is ejected, allowing the cycle to start again.

Which Kinds of Resins and Tools Are Available? ​

S136H, 2316H, H13 hardened, P20, 8407, and NAK80 semi-hardened steels are used to create our tools and dies. We provide a variety of etched textures, EDM texturing, and typical SPI finishes. Additionally, thousands of thermoforming plastics are available for your projects.

Material Selection for Plastic Injection Molding ​

The primary consideration when selecting a plastic is the part's intended use and the physical conditions it will encounter, such as temperature fluctuations, moisture, chemical exposure, UV light, and many more. The strength, durability, flexibility, color, and cost of the material are then factors to consider. For most parts, we use the 10 most popular plastic injection molding resins: ABS, PBT, PEEK, polyethylene (PE), polycarbonate (PC), polypropylene (PP), nylon (PA), acrylic (PMMA), polystyrene (PS), and TPE.
