Molds and presses are two key factors in determining stamping quality, precision and productivity. Advanced presses can only be fully functional and achieve good results if they are equipped with advanced molds. The development direction of the mold is:

First, make full use of IT technology to develop mold design and manufacturing. The ever-increasing demands of users on press speed, accuracy, and mold change efficiency have promoted the development of molds. The shape of the body and the engine are two key components of the car. The car body mould, especially the large and medium-sized cover mould, is technically intensive and reflects the level of contemporary mould technology and is an important part of the body manufacturing technology. The design and manufacture of body molds accounted for about two-thirds of the car development cycle and became the main constraint for car replacement. At present, the replacement of the world's cars is about 48 months, while the United States only needs 30 months. This car benefits from the application of CAD/CAE/CAM technology and 3D solid steam cover in the mold industry. Mold structure design software. In addition, the wide application of network technology provides a reliable information carrier, enabling off-site design and off-site manufacturing. At the same time, the application of IT technology such as virtual manufacturing will also promote the development of the mold industry.

Second, shorten the trial time of metal forming molds. At present, the development of hydraulic high-speed test presses and tensile mechanical presses, especially on mechanical presses, can be reduced by 80% and has enormous potential for savings. The development trend of this type of test-type mechanical press is to use a multi-link stretching press equipped with a numerically controlled hydraulic stretching pad with parameter setting and state memory function.

Third, the progressive die in the body manufacturing has developed rapidly. It is a well-known stamping technique to use a progressive punching die or a combination die to machine a rotor or a stator plate on an automatic punching machine, or to apply it to a connector. In recent years, progressive die-cutting die has begun to be obtained in body manufacturing. More and more widely used, the progressive die is used to directly process the coil into molded parts and tensile parts.

The processed parts are also getting larger and larger, eliminating the need for subsequent processes such as cutting, oiling, and slab transportation of the plates that must be connected in series with multi-station presses and complete sets of molds. Progressive combination dies have been commonly used in the automotive industry in the United States, with the advantages of high productivity, low mold cost, and no need for sheet shearing, saving 30% compared to step molds used on multi-station presses. However, the application of progressive combination die technology is limited by the depth of the stretch, the surface hardening of the strip material of the guiding and transporting, and is mainly used for simple parts with shallow drawing depth, so it cannot completely replace the multi-station press. Most parts should be considered for processing on multi-station presses.
