With SOLIDWORKS Plastics, users will be able to tackle complex injection-molding challenges in software —rather than through costly, time-consuming prototyping iterations and achieve their product development and manufacturing objectives.

Ease of Use

SOLIDWORKS Plastics is fully embedded in SOLIDWORKS 3D CAD for ease of use and data integrity. Using the same user interface (UI) as SOLIDWORKS in toolbars, menus, and context-sensitive right-click menus ensures rapid familiarization. Built-in tutorials and searchable online help aid learning and troubleshooting.

Design Data Reuse

SOLIDWORKS Plastics supports SOLIDWORKS materials and configurations for easy analysis of multiple loads and product configurations.

Materials Database

With 4,000+ commercial thermoplastic grades, you can browse and select the desired from the customizable built-in material library.


SOLIDWORKS Plastics includes these meshing features:

  • Wizard for mesh generation and analysis setup
  • Automatic Mesh
  • Local Mesh Refinement
  • Global Mesh Refinement
  • Boundary Mesh (Shell)
  • Solid 3D mesh
Parallel Computing (Multi-Core)

The 3D Solver benefits from a multi-core CPU (multiple threads).

Filling Phase (1st Stage Injection)

Predicts how material fills the cavity. Results include distributions of pressure and temperature within the cavity, and detection of potential short shots and weld lines.

Automatic Gate Location(s)

Defines up to 10 injection locations on the part cavity automatically. SOLIDWORKS Plastics adds injection locations onto the part based on the geometry and optimized balanced fill pattern.

Instantaneous Fill Time Plot

Predicts the plastic flow pattern through the cavity at the end of fill.

Sink Mark Analysis

Predicts the depth of sink marks after the part has been ejected and cooled to room temperature.

eDrawings Support

Results can be exported to eDrawing®

Fill Time

Time needed to fill the whole mold.

Ease of Fill

Displays the quality of the injection process with ‘confidence of fill’ legend.

Results Adviser

User assistant for interpreting results.

Nominal Wall Thickness Adviser

Analyzes the part thickness and locates the high thickness ratio.

Pressure at End of Fill

Displays the maximum pressure to fill the cavity.

Flow Front Temperature

Displays the melt front temperature history.

Temperature at End of Fill

Displays the Cavity Temperature field at the end of fill.

Shear Rate

Displays the shear rate reached at the end of fill to check the injection process quality.

Cooling Time

Estimates cooling time at fill time analysis.

Weld Lines

Displays weld lines formed at locations of the part where two (or multiple) melt fronts meet.

Air Traps

Shows the location where high pressure air may be trapped inside the cavity.

Sink Marks

Displays the location of sink marks.

Frozen Layer Fraction at End of Fill

Displays the fraction of frozen material into the part at end of fill.

Clamp Force

Displays the minimum clamp force for the current injection process.

Cycle Time

Displays the cycle time for the current injection process.

Symmetry Analysis

Avoid simulating both cavities in a symmetrical mold layout, saving computer time for the simulation.

Packing Phase (2nd Stage Injection)

Evaluates the material freezing process in the cavity. Predicts the temperature to evaluate hot spots, gate freeze, and cycle time. Distributions of pressure, stress, and shrinkage results are also available.

Runner Balancing

Determines the runner parameters to balance filling between parts.

Runner Design Wizard

Automates the process of creating common flow control devices and components such as sprues, runners, and gates.

Sprues and Runners

Quickly and easily simulate the impact of the sprues and runners layout.

Hot & Cold Runners

Hot runners are initially filled with hot polymer at the start of the filling simulation.

Multi-Cavity Molds

Simulates multiple cavities of the same part in the same mold.

Family Molds

Simulates a set of different cavities parts in the same mold.

Mold Inserts

Include the impact of mold inserts on the simulation

Volumetric Shrinkage

Displays volumetric shrinkage distribution at the end of fill or pack.

Density at End of Pack

Displays density distribution at post-filling end to check the pack phase quality.


Enables you to export part geometry in STL or NASTRAN formats

Export with Mechanical Properties ABAQUS®, ANSYS, DigiMat®

Exports mesh, residual stress, fiber orientation and material data to run non-linear analysis.

Cooling Lines

Simulates the coolant flowing inside for the mold cooling analysis.

Baffles & Bubblers

Specific cooling line for narrow channel into the cavity.

Conformal Cooling Channels

Cooling passageway follows the shape or profile of the mold core or cavity to perform rapid uniform cooling process.

Runner Domain Category

Domain category assigned to the runner allows easy selection for runner’s conditions.

Sink Mark Profiles

Displays the location of sink marks and their depth.

Mold Temperature at Cooling End

Displays the mold temperature distribution at cooling end.
