The most cost-effective time to optimise plastic parts for manufacturablity is during the initial stages of product design. Skipping this step can often lead to an inefficient mould design with an extremely narrow "good parts" processing window, resulting in high reject rates and time-to-market delays.

The cost of making changes early on in the design process is relatively low, but the impact is at the highest level. The sooner you optimise your plastic parts and injection moulds for manufacturability the better. The later you leave it the more the cost of change increases further downstream, and could lead to significant time-to-market delays.

The challenge in plastics part production is determining how your part or mould design impacts upon manufacturing, and how manufacturing impacts upon your design, as early as possible, and communicating this as early and frequently as necessary through the whole design-to-manufacture process. SOLIDWORKS Plastics provides all the tools you need to quickly identify any potential problems so you can make changes early in the design process.

For designers of plastic parts or injection moulds, SOLIDWORKS Plastics simulates how melted plastic flows during the injection moulding process, to predict manufacturing-related defects on your parts. Once identified, defects can be easily minimised or eliminated altogether by making changes to the part design, mould design, plastics material or processing parameters, saving energy, natural resources, time and money.

Fully integrated in the SOLIDWORKS environment, SOLIDWORKS Plastics Professional will analyse and modify designs for manufacturability whilst at the same time optimising for form, fit and function.


SOLIDWORKS Plastics is available in three versions, with SOLIDWORKS Plastics Standard for optimising parts for manufacturability in the early stages of design, SOLIDWORKS Plastics Professional being ideal for plastics part designers, and SOLIDWORKS Plastics Premium being perfect for mould designers and mould makers.

SOLIDWORKS Plastics ​Standard - for plastics part optimisation

Easy to learn and use, full embedded within the SOLIDWORKS CAD environment.

  • Analyse and modify designs at the early stages
  • Optimise for form fit and function

SOLIDWORKS Plastics Professional - for plastics part designers

Answers the basic questions around whether your part will fill, where are the weld lines and will there be air traps?

  • Simulates the mould filling stage
  • Optimises part designs for manufacturing
  • Determines the best gate location(s)

SOLIDWORKS Plastics Premium - for mould designers and mould makers

SOLIDWORKS Plastics Premium gives anyone designing or building injection moulds an accurate, easy-to-use way to optimise them. Quickly create and analyse single, multi-cavity and family mould layouts, including sprues, runners and gates. You can even balance runner systems and estimate cycle time, clamp tonnage and shot size.

  • Simulates the filling and packing stages
  • Optimises single and multi-cavity mould layouts
  • Automatically balance family mould runner systems
  • Determine maximum injection pressure requirements and machine size
  • Simulate advanced analysis of insert overmoulding, 2-shot moulding, gas-assist and valve gates
