Mold-flow Analysis

With the need to streamline the design, development, and manufacturing of a plastic injection mold, Mold-flow simulation is an extremely valuable tool. By using the Mold-flows line of plastic products, our SWY MOULD team can predict how part geometry or multiple parts within the same tool will affect the injection condition, supply the hot runner manufacturer with bore sizes, balance the runner-based on tooling conditions and troubleshoot an existing plastic mold.  This simulation software allows to design and optimizes plastic injection mold through the creation of gate and runner systems, and to predict the flow of materials, filling and packing pressure, cycle time, shot size, and clamp tonnage.

SWY MOULD has Mold-flow analysis provided for our customers. We know how to choose the best configuration such as runner, gate position, and cooling system in order to optimize the mold structure and enhance production efficiency. The lead times on the design and manufacturing of tooling have been dramatically decreased, and the need to take first sample parts immediately into production is inevitable.  Having the same team develop the mold design and the mold flow analysis will solve the problem of last time in the attempt to complete a mold flow analysis using practical manufacturing constraints, therefore, bring the project to manufacturing more efficiently and in a timely manner.

The main content of Mold-flow Analysis:

1. Fill analysis

Balanced fill, Gate location, Number of gates required, Gate/runner sizes, Location of weld lines, Shear rate / Shear stress, Valve gate timing (if required), Fill pressure, Melt front temperature, Processing conditions

2. Pack analysis

Clamp tonnage, Packing profile, Density, Volumetric shrinkage

3. Cool analysis

Cooling time, Coolant temperature, Verify cooling lines achieve acceptable part cooling, Cycle time

4. Warp analysis

The amount of displacement in the X, Y, and Z directions, Part shrinkage

Advantages of Mold-flow Analysis: 

1. Faster cycle times 

2. Reduce clamp tonnage 

3. Produce better quality parts 

4. Speed up project progress 

5. Reduce the number of mold tests 

6. Deliver your parts on time

In the part or mold design phase of your project, our engineers will explore with you all aspects of your process. Based on your specific molding requirements, we then run a fill, pack, cool, and/or warp analysis and deliver our feedback in a detailed report outlining improvements and optimization.
