Aging and heat treatment of mold forming parts
- The forming parts of Sweden ASSAB S136 domestic factory to aging, heat treatment hardness: HRC52 degrees, provides great wear resistance of mold, the service life is obviously enhanced, all sliding parts contact surface inlaid self-lubricating wear-resistant copper alloy.
Mold forming part structure
- The structure of main parts are the same with foreign well-known brands, remove flexible and rapid, convenient for maintenance. Mold processing time increased 30%, but the removal and maintenance time reduced 50%. With double cone positioning principle and processing ability of high accuracy, so that can down the changeable factors to the bottom
Hot runner structure
- The cylinder piston flew with the hot runner, won't accure the core difference of the valve needle and the mold cavity because of the expanding due to the hot runner heating up, and the cylinder and the hot runner plate is not a precision fit structure, can be arbitrarily disassembled, easy to maintain. The components are the same as the international famous brand molds, and the parts can be interchangeable.
Hot runner temperature control structure
- The hot runner is equipped with an independent person responsible for the assembly, there are standard operating standards and testing procedures, with the multi - point and multi - layer balanced filling structure, to ensure the consistency of each mold cavity injection schedule. Hot runner uses the embedded square heating tube heating, the heating pipe around the shape of the runner layout, with fantastic heat transfer, can ensure that the temperature's consistency of the injection point. While with the special nature of the design, make the heat expansion coefficient to the lowest point, make sure the accurate of each injection point's location, AA value stability.
Precision of mold processing
- Spare parts is processed in the stable temperature workshop, through the German DMG six-axle turning and milling composite machine and CNC grinding machines and some other high-precision equipment, dense processing equipment with heat pipe around the shape of flow channel layout, with better heat transfer. Adopt the three Coordinate detector for inspection to ensure the dimensional accuracy error of parts processing reach only 0.01mm.
The weight deviation of the whole mold preforms
- Since the improvement of the processing precision and the reasonable design of the hot runner system, the weight deviation of the same mold down to 0.2 gram.
Production cycle time
- Mold structure, optimization of waterway structure and balanced injection of hot runner, the production cycle efficiency can be increased more than 15%.
Life time
- High-precision machining conditions and material properties, hardness and other enhancements to ensure the stronger wear ability of the mold, so the mold normal life of up to 300 million times which is applicable to high-speed and high-efficiency injection molding system.
Use cost of mold
- Since the update of the hot runner technology and spare parts hardness, the annual normal maintenance costs over the warranty period is about 2%. Since the change of structural, exhaust function has been greatly improved, with the stabile hot runner system, reject rate only reach 0.3% or lower.
