Mirror plastic mold steel PMS is a precipitation hardening type aging steel with excellent mirror processing performance, good hot and cold processing properties, electrical processing properties and good comprehensive mechanical properties. The heat treatment process is simple, and after solid solution at 85O ± 20 °C, the matrix is ​​bainite and martensite dual phase structure after aging treatment at 5000 ± 10 °C, and the heat treatment deformation rate is small (≤ -O.O5%). The section structure of section ≤ Ф15Omm or stencil thickness ≤15Omm has uniform hardness distribution. Mechanical properties: σs>980MPa, σB>1200MPa, δ5>13%, ψ>45%. Applicable to the production of working temperature of about 300 ° C, the use of hardness HRC3O-45, requires high mirror, high precision of various plastic molds.
PMS mirror plastic mold steel has good nitriding surface strengthening properties. The surface hardness after nitriding treatment is HV8OO -1200.
PMS steel is widely used in optical systems for a variety of lenses, audio and video tape inside and outside boxes, telephones. Various plastic housing molds such as tape recorders, quartz clocks, washing machines, vehicle lamps, and instrumentation appliances.
Rapid Tooling Technology Type Rapid Tooling Technology is a fast, convenient and practical mold making technology. The characteristics of this technology are: short molding cycle, simple process, easy promotion, low molding cost, accuracy and longevity to meet certain specific functional needs, and comprehensive economic benefits. It is especially suitable for new product development and trial production, process verification and functional verification, as well as multi-variety and small batch production.
Due to the increasingly fierce market competition, the speed of product upgrading is accelerating, and many varieties and small batches will become important manufacturing methods in the manufacturing industry. Under this circumstance, the manufacturing industry has strongly promoted the rapid manufacture of prototypes and the rapid manufacturing of molds. Requirements. Therefore, rapid molding technology presents a dynamic development trend.
At present, there are mainly the following rapid mold-making techniques applied in practice:
1. Modeling method based on rapid prototyping technology. This method is based on the novel discrete/stacking (ie, material accumulation) molding idea, using stereo light curing, laminated solid system, laser selective sintering, three-dimensional printing, fused deposition molding and other methods to obtain long-life metal molds or non- Metal low life mold. This method has the characteristics of advanced technology, low cost, and short design and manufacturing cycle.
2. High-speed machining of molds. At present, the speed of high-speed cutting machine tools widely used in production is about 1.5 to 25,000 rpm. The use of high-speed cutting can increase the processing efficiency by more than 10 times, which can greatly shorten the molding time. The mold surface after high-speed machining and finishing can be used only with a little polishing, which saves a lot of grinding and polishing time.
3. The plastic mold is made of aluminum alloy material. Aluminum alloy materials have been used more and more in the manufacture of plastic molds in recent years due to their excellent properties such as light weight, good cutting performance and high thermal conductivity. The use of aluminum alloy materials to make molds can achieve good results in shortening the molding cycle and reducing costs. Foreign manufacturers have produced aluminum alloy materials for plastic molds. The plastic mold made of aluminum alloy has a service life of up to 100,000 times. If the surface of the cavity is chemically treated, the service life can reach 200-30,000 times.
