Mass Production/Low Cost per Part – The ability to mass-produce products consistently is the key benefit of the injection molding process. The manufacturing cost per piece is inexpensive once the capital expenses are paid. The process is quite desirable as product prices tend to drop drastically as more parts are produced.
Low Scrap Rates – The injection process produces relatively low scrap rates compared to traditional manufacturing processes.
Product Consistency – The injection molding process is known for its repeatability and consistency, making it ideal for mass production.
Efficient Process – This process is fast, consistent, and has rapid cycle times. Multi-cavity molds further increase the rapid production cycle.
Material Selection
A large selection of materials is available for the molding industry. In addition, plastics, rubber, and silicone are available materials.
Dimensionally Accurate
Parts can be produced to tight tolerances. Dimensional tolerances of +/- 0.005" are not uncommon.
Little/No Post Processing
Typically, minimal post-production is required.
Plastic Injection Moulding Types

Standard Injection Moulding
The most common method. Thermoplastic resin pellets are fed into the injection moulding machine, melted, injected into a mould, cooled, and ejected as a solid part. Used for high-volume production of parts.

Two-Shot Molding
Two-shot molding, 2K shot molding, or dual-shot molding produces complex moldings from two materials during a single cycle. This process is beneficial when different properties are desired in different areas of the part.

Overmolding
A secondary plastic is an injection molded over a primary plastic part already in the mould. Creates a two-material part with an inner core and outer layer. Used for grips, buttons, seals, etc.

Insert Molding
Inserts made of metal, ceramics or other non-plastic materials are placed in the mould cavity first before injection of molten plastic. Useful for electrical or mechanical parts.
