Thermoplastic Injection Molding: A Brief Description

Thermoplastic injection molding is the most widely used of all plastic processing methods. Injection molding is a manufacturing technique for making parts from the plastic material. Molten plastic is injected at high pressure into a mold, which is the inverse of the desired shape.

Once formed, thermoplastics can be heated and reformed over and over again.

Thermoplastic Injection Molding: A Top-Quality Mold is Key

Injection molding offers the lowest piece prices available, but tooling (mold making) prices are generally the highest.  Since we have our own plastic molds manufacturing company so that we will offer our customer the lowest cost for mold making and the highest quality molds for our customers,

GC MOLD’s advanced design and engineering techniques produce the highest quality plastic molds available today. And they stand behind their word. They offer their customers the option of joining their Extended Warranty Program guaranteeing the mold BMJ designs and builds will retain its integrity throughout a specific number of cycles.

Thermoplastic Injection Molding: Applications

Injection molding is very widely used for manufacturing a variety of parts, from the smallest component to entire body panels of cars. It is the most common method of production, with some commonly made items including bottle caps and outdoor furniture.

Thermoplastic Injection Molding: Mold Options

While there are a variety of mold options, the choice is usually determined by the type of part and final application properties needed, as well as a number of other factors (see the GC MOLD webpage Quotation Process for more information) including:
(click on names for more information)

• Hot Runner Molds – shoots material directly into individual cavities; eliminates the runner for reduced material cost and less handling
• Cold Runner Molds – injects material into a runner system that redirects it into individual cavities; lower initial start-up cost than Hot Runner
• Insert Mold – an “over-mold” to mold plastic around other materials, such as brass, steel, aluminum, or even other plastic inserts, such as sleeves for drill housings, latches, and screen mesh buffer tubes
• Two-Shot Molds (also 1-Shot, 3-Shot and 4-Shot Molds) – a cost-effective way to produce parts with 2 or more colors molded at the same time; eliminates a secondary process to add logos, graphics or text.
• Stack Molds – high production molds for multiple parting lines; can produce multiple types of parts more economically over a large production run
• Unscrewing Molds – to produce parts with internal or external threads, such as nuts, nut augers, sprinkler heads
