The trend of sports shoes has not only paid attention to the shape design and popularity, but also the function and comfort have become one of the key points.

Especially the sole parts, the famous brand shoe manufacturers have spared no effort to invest in R & D and innovation.

The shoe sole mould factory therefore needs to face the change of the free-form surface of the shoe type, shorten the product life cycle and enhance the quality. In order to meet the market demand, it is bound to enhance the design and manufacturing technology of the shoe sole mold.

As a professional CAD/CAM/RE software development company, silver network has seriously analyzed and studied the mold manufacturing problems faced by the shoe mold industry. As early as 2002, it launched a complete sole model model tailored to the shoe mold industry, specializing in developing and mass production innovative technology.

In the aspects of grading, IP shrinkage, machining path planning, model design change and so on, the best solution for shoe sole mold is provided, so as to shorten the die delivery time and improve the quality of shoe mold industry.

Because the system is easy to import and effective, many shoe manufacturers have been trusted and affirmed.

The technology of shoe sole 3D CAD/CAM is the core of the shoe industry, and its technical requirements and specialization are quite high. However, the CAD/CAM system in the past has been unable to meet the needs of shoe mold manufacturing development.

In view of the fact that CAD/CAM system suppliers have never been able to break through the restrictions on the understanding of shoemaking process, silver net technology is determined to invest in this field and take "professional customization" as the goal, integrate the relevant industry knowledge into the CAD/CAM system, and develop the Complete Shoe Sole Solution.

"At present, the market demand of shoe mould CAD/CAM is aimed at shortening the training time and production cycle of employees, so as to achieve the goal of rapid manufacturing and first listing, which is the key to success in the market," said Liu Lun Li, director of the mold division of Baocheng group.

The sole design direction of the sole model system is to standardize and simplify operations, so that operations can be reduced to one or two steps. Instead of using the ubiquitous system, every job needs to be done step by step. In addition, because the other parts of the process are linked together to build an automated workflow, the job engineer does not need to spend too much time training too much, just follow the instructions.

That is to say, the introduction of the shoe sole model professional system can greatly shorten the learning time and operation steps of the personnel, and help manufacturers save time for manufacturing and management.

Complete Shoe Sole Solution is a complete set of shoe sole model development and mass production system developed by silver net. It is completely custom-made and develops for the functions that customers need.

The design of software is easy to learn and easy to use, and silver net technology provides the most complete education and training service, allowing the industry to go on the fastest and shortest time.

Shoe Wizard—快速級放系統

The sole CAD model takes shape and functionality into consideration. It has free-form surfaces and is composed of many objects, such as midsole, outsole, ejection film, air bag and so on.

When a single size model is confirmed, there are specific adjustment and locking requirements when generating models of various sizes and sizes. For example, the meat thickness should be consistent, the thickness of the side wall should be consistent, the special shape should be maintained, and the parts should be shared.

It will take a lot of time and a lot of manpower to complete the work in the establishment of the full head 3D CAD. Because of the complexity of the work, the quality of the 3D models is unstable, which makes it difficult to accomplish the mass production of the 3D model.

ShoeWizard is a system specially applied to the grading system (Fig. 2). After completing the CAD model of the standard code shoe, the relevant size parameters are set and the specified change mode is set, and a full size 3D model is automatically generated by a single size, which can greatly shorten the working time of the stage.

ShoeWizard uses flow tooling to guide the operator to use ShoeWizard. After selecting objects, the parameters are set, the size of the grading and the specified changes are selected, and the full number 3D model is automatically generated after completion of the lock.

Only one step of operation according to the tool list can quickly complete the work of grading.

The sole molding process can be described as the most time-consuming and difficult part of the footwear industry at present, because the shoe mold involves the precision mold manufacturing process.

ShoeWizard has solved the problem of the existing industry, and designed the locking function for the development of shoe sole mold, making the work of the stage easier and more precise, so as to meet the demand of the shoe mold industry with fast and mass production.

The effect of execution can produce the consistency of product quality and shorten the processing time (Table 1).

Replace Wizard—簡易置換系統

The models of sole models are often modified due to factors such as designer's design change, last replacement, and process / accessories needs before determining mass production.

When dealing with a general CAD system, it is necessary to make modifications and adjustments on curves or surfaces, so engineers must spend a lot of manpower and time to make modifications.

Replace Wizard is a replacement system needed for the design of shoe sole die, which can be completed quickly and accurately, and can meet the adjustment from product design to mold manufacturing.

After replacing the die curve and setting the relevant locking condition and auxiliary line, the system automatically performs the replacement (Figure 3, 4) and the movement between the locking and the surface smoothly, and realizes the design change requirement quickly, greatly reduces the modification operation time, and improves the correctness of the model modification and the quality of the model.

EVA Magician precision die reduction system

The EVA material has the characteristics of light weight and shock absorption, and can be produced in large quantities in the way of ejection, making EVA widely used in the sole of the sole.

To make EVA moulds, we need to effectively control the foaming characteristics of EVA materials and the conditions of injection molding environment. The process is complex and difficult to control.

In the past, model building requires manual calculation of foaming rate, and 2D and 3D designers need to repeatedly communicate with each other to check, adjust, or rebuild.

Usually the first die is only a trial mold, and then remoulds or moulds according to the test results, accumulating EVA mold development experience from mistakes.

However, there are many variables that affect the development of EVA mold, and the coordination among different units is not easy, the development time is very long, and the probability of completing the mold at a time is low, which leads to the high cost of mold development.

ShoeCAM intelligent CAM system

In the process of shoe mould processing, the path planning of shoe mould is rather complicated, mainly because the relationship between free form surface modeling and complex pattern design is at the bottom, front, back and back and inside and outside of the wood mold.

Shoe mold processing is generally done by three axis and five sides, and the design of tool path will affect the processing time and processing quality of shoe mold.

Besides the work of general path planning, it is necessary to set up additional files such as files, lines and so on, which will lead to a lot of complicated work.

Therefore, the traditional shoe mold processing often relies on experienced engineers, resulting in a large dependence on personnel. Once experienced engineers are lost, it will cause great trouble for manufacturers.

ShoeCAM is a system that quickly and simplifies the three axis and five face tool path, and standardize and automate the machining process of shoe mould in the system.

There are further functions in operation interface, tool setting, rough machining, residue analysis, residue processing, finishing and path editing. (system comparison is shown in Table 2).

Especially in the operation interface, it has simplified options, easy to learn and easy to operate. As long as "One Button", the tool path planning of shoe mold can be completed.

CAD/CAM future trend

In view of the bottleneck of ubiquitous CAD/CAM, CAD surface construction and operation are complicated, and the quality of each model is inconsistent after grading. CAM has complicated operation and long processing time, so it is necessary to train professional CAD/CAM personnel for a long time.

For this reason, the continuous innovation research of silver net has developed a complete shoe industry special function with advanced 3D computer aided design and manufacturing technology, integrating sole molding process and professional knowledge, to meet the demand of complex shoe sole design and various shoes.

The automated workflow built by Complete Shoe Sole Solution enables the whole number of wooden models to be completed within 2 weeks, effectively shortening the manufacturing schedule.

Plus humanized operation interface design, simple, easy to learn, and quickly train professional talents in the footwear industry, in 2 weeks can be imported on-line, not to worry about the flow of personnel and technology inheritance and other issues.

The development direction of CAD/CAM software in the future will be the trend towards customer-oriented tailored system, emphasizing whether the process of design, manufacturing and testing can operate effectively and whether the function is complete.
