Hot Stamping Tool, 2k & Double Injection Molding

Some time ago, our company and a strategic customer developed a product with 60% glass fiber jointly. Which may replace the metal parts and reduce the weight of the body. That is a major technological innovation in  hot forming die , hydroforming die, Acute hot mold. Please look forward to!

As we all know, Shinlone is a professorial company of  TV mould . Here I will tell you the reason of people's choice. We adopt the following QC procedure to ensure quality of world-wide standard. 1) Inspection for mould material hardness 2) Inspection for mould size 3) Inspection for size of cavity and core 4) Inspection the whole mould before and after assembly 5) Report for mould trial and sample 6) Final inspection before delivery 7) Package inspection before delivery If you need  TV mold , please contact us via  young@shinlone.com.cn .

Hot forming die  is a temperature- and time-dependent process. With this method, parts are formed in their soft state at elevated temperatures and then quenched in the tool. The hot forming process consists of the following steps: Heat treatment in furnace Transfer from furnace to press and drawing tool Plastic hot forming Quenching in the closed, cooled die Parts produced by  hot forming tools  are characterized by high strength, complex shapes and reduced springback effects. Optimal material behavior is achieved through the structural transformation of austenite into martensite. The most commonly used material in hot forming is Boron steel 22MnB5, which is available from many steel manufacturers.

The direct  hot forming die  process is a three-stage approach. After heating up to 950 °C a blank is transferred to the pre-conditioned forming tools. Then the part is formed in an austenitic state. Afterwards the part is quenched in the colder tools. Applying a defined tonnage or engineering a specific gap between tools and the blank heat transfer conditions are adjusted. During this process stage the temperature in the blank drops from around 950 °C initially down to 200 °C. The average temperature of the tool in use is maintained near 80 °C. During this stage the transformation to a martensitic phase is driven by controlled heat transfer conditions that lead to characteristic cooling curves and therefore to final values for yield strength (YS) and ultimate tensile strength (UTS). Trimming the blank can be executed either directly in the tool or by means of a subsequent laser trim operation. We can provide  high quality hot forming tools , if you need, you c...

There are  hot stamping tools  in market, why? Here I will tell you the reason. In recent years, the automotive industry is making an effort to reduce the vehicle weight in order to reduce the CO2 emission while maintaining high strength properties of vehicle components. For lightweight construction, the demand of ultra high strength steels is drastically increased. To increase the formability and reduce the high spring back, hot stamping with ultra high strength steel is becoming more popular in automotive industry. In hot stamping, blanks are hot formed and press hardened in a water-cooled tool to achieve high strength. Hence, design of the tool with active cooling system significantly influences the final properties of the blank and the process time. However, the achieved high strength causes severe tool wear at the blanking of the hardened parts in a serial production with conventional mechanical cutting methods. Because of high costs for repairing of the blanking...

As many industries become increasingly aware of the benefits of metal-to-plastic conversion,  high-volume double injection molding  is quickly becoming the method of choice for part manufacture. Plastic parts offer several universal benefits over metal, including: Can have higher tensile strength vs. many types of metal  Reduced part weight  Reduced manufacturing costs  Superior design flexibility  Reduced waste  Faster manufacturing times  Easy adherence to various regulatory compliances  Lower packaging and shipping costs  Up to six times longer life  Increased corrosion resistance  Repeatable, predictable manufacture Besides reducing weight and improving overall part strength and corrosion resistance, plastic-to-metal conversion also allows for the consolidation of multiple metal parts into a single plastic part. And aside from offering equal toughness and allowing for the same t...
