We believe that quality begins with mould design capability and consider it to be the key to mould making. At SWY MOULD, we have invested in both people and technology to ensure that our design meets your highest expectations. A good design is the heart of a mold, therefore, we especially focus on the mould structure: cooling, venting, and moving mechanism are the preconditions to achieve the high-quality molds and short molding cycle time. All moulds are carefully designed, from the parts analysis to the molds general assembly and assessment of part processing, we organize project engineers, designers, mold makers, and technical directors to participate in the project evaluation conferences more than three times for each mould. With the above efforts, we do our best to maximize mould life and minimize maintenance work.
We are in accordance with the international standards, such as DME, HASCO, Progressive, DAIDO, or customers’ specific standards, to ensure each designed mold be able to be well-run in the designated country. Matching customers’ file formats, we provide DXF, DWG, PRT, IGES, STEP, X-T, and other file formats to customers.

* AutoCAD (2D Modeling)
* MoldFlow Mold Advisor (Plastic flow/deform simulation)

DFM is an acronym for “Design For Manufacturability”, which means we extensively study the 3D/CAD files you provide and make sure your design can be built as you intended. Then we will provide you a report for each part that summarizes the part information (size, weight, material, finish, color, etc.) and addresses any concerns regarding mould making or part design. Not only that, but the DFM we provide also includes our recommendations on how to resolve any issues best to help you revise the design if necessary. In every manufacturing process, it is essential to ensure that every stage is foolproof and executed appropriately. From material selection all the way to actual manufacturing, it is essential to find a balance between cost and quality. In the injection molding process, the injection molding design for manufacturability(DFM) is the process that ensures all the above is adhered to.
Injection molding design for manufacturability basically has to do with the improvement and enhancement of your part design. It ensures that your part is economically fit for production, easy to produce, and fulfills its functional duties. However, DFM doesn’t only deal with the injection molding design. It also covers selecting the suitable materials, the injection molding mould design, evaluating product lead time, quality, hazard associated with use, and so on.

Five principles of DFM:

Process, design, material, environment, compliance/testing.

Advantages of DFM:
* Quicker lead time
* Quicker time to market
* Reduction of production cost
* Higher quality of parts
* Reduces wastage

The importance of DFM:
* Guarantee of manufacturing feasibility
* Prevention of part failure
* Determination of the complexities of manufacturing

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.
