                                                                                                             Injection Moulding Process

      Rapid injection moulding is a low-to-mid volume plastic part production process. After the part’s  
      design is finished, a mould is created and machined with precision to form the part’s features. 
      The mould is installed into an injection mould press, and molten plastic is injected into the mould 
      tool under pressure. The part is then cooled, ejected, and the process repeats.

     Injection Moulding Process Considerations

      Warping: When certain sections cool and shrink at different rates in different directions, it can 
      result in permanently bents in parts due to internal stresses.
      Sink Marks: When a section shrinks faster on the outside than on the inside, it can cause the 
      material to collapse in on itself, resulting in sink marks.
      Drag Marks: When the plastic is injected into the mould, it flow along the walls of the mould  
      cavity. The plastic then cools and solidifies. During ejection, the walls of the part will slide and  
      scrape against the mould, which can result to drag marks.

injection Moulding FAQs

What is injection moulding?
Injection moulding is a mature manufacturing process that allows for plastic parts to be produced in large volumes. The process involves melting plastic pellets that once
malleable enough, are injected at pressure into a mould cavity, which fills and solidifies to produce the final product.

How much does injection moulding cost?
Mould Cost: Typically, the tooling costs is between $2,000 – $10,000. However, depending on the complexity of the project, type of tool, and other factors, it can go well
over $10,000.
Part Cost: The unit cost is what makes the initial investment in injection mould worthwhile. You can expect the cost per unit from $.01.

How long does an injection mould last?
Injection mould tools can last between 100 to over 100,000 and even 1M+ cycles. The life span of an injection mould depends on the mould material, mould structure
design,maintenance, time between production runs and operating conditions.
