Hardened steel: Typically the most expensive material to use for a mold, and generally the longest-lasting (which can drive down price per unit). This makes hardened steel a good material choice for products where multiple hundreds of thousands are to be produced.
Prehardened steel: Does not last as many cycles as hardened steel, and is less expensive to create.
Aluminum: Most commonly used for single cavity "Prototype Tooling" when a relatively low number of parts are needed for testing. Once the injection molded parts from this tool are tested and approved, then a multi cavity steel production tool is produced. It is possible to get many thousands of parts from an aluminum tool but typically it is used for lower quantities.
Beryllium-Copper alloy: Typically used in areas of the mold that need fast heat removal or where shear heat is concentrated.
Just as with overall product design, mold design is another opportunity to prevent defects during the injection molding process. We have previously written blogs on the Top 10 Injection Molding Defects and Avoiding Mistakes in Injection Molding, but here are some examples of how poor mold design can be a costly mistake:

High efficiency, Energy-saving and high precise proportional pressure and flow variable displacement pump system make the out of the hydraulic system matching the required power for entire machine operation without loss of high pressure throttle and overflow energy. As comparedwith constant displacement pump, t saves power by 30%~60%.A motor with same power may be fitted with an oil pump of bigger displacement and thus accelerates the speed of machine.Besides, the low oil temperature will prolong the service life of sealing elements.
Buffer device is used in every mold opening and clamping oil way to ensure steady mold opening and clamping operation without any impact.Besides, differential mold clamping operation is fitted to ensure high production efficiency.
High Energy saving
Under the ideal working state, Power consumption is 40% less than that of variable displacement pump and 70% less than that of fixed displacement pump, save the cost effectively.
High precision
Precise control of low pressure & low flow, repeating precision is less than 0.5%. Weight error of the products is 0.4%~0.7%, with semi-close loop system nearly.
Fast response
With steady capability, servo gearshift dynamical control system has equipped with pressure feedback device with high precision and sensitivity, which forms close-loop precision control, cycle time effectively shortened and improving production efficiency.
Oil temperature rise slowly
The system can restrain arising of oil temperature, so smaller oil cooling system can be used in the machine.
PQ control
Control pressure and flow simply by inputting simulated voltage of pressure & flow into the computer.
Low noise
Different from ordinary fixed pump injection molding machine, servo power-saving injection molding machine is working only when necessary. And working noise is less than LOG-A8 series, will be much quieter for your working area.
