Key Elements Brands of LZ high pressure die casting aluminum molding machine:

(Remark: Aluminum Molding Machine Spare parts brands can be changed as per customer demand. The producer of die casting machine-LZ (China) keeps the right to revise above parameters. If there is any alterations, advance notice won't be given then. Die Casting Machine spare parts brands can be changed as per customer demand.)

1. DDC system and fast accumulation system, which shorten production cycle efficiently.

   

2. Central electrical lubrication system.

   
   

3. Hydraulic driven gear-type mould height adjusting mechanism.

   

4. Four stages control of injection speed and pressure, independent high-speeding intensification injection accumulators. Quality accumulator in die casting machine insure the pressure output stable, strong, fast. Two intensification activation ways: position way and pressure way.

   

5. High rigidity molding platen, high tensile alloy steel hard chrome plated tie bar.

   

6. PLC control system (with touch screen) with fast, stable, safe and reliable operation, high precision, and functions such as production management, trouble diagnosis, and 50 sets mould parameters storage.

   
   

7. High speed hydraulic ejection and core-pulling devices.

   
   

8. Electrical proportional control of system pressure and flow, with multi-stage pressure and speed control, and low-pressure die close protection function.

   
   

Realtime Control System of High Pressure Die Cast Machine

• Accurate Close Loop Control Technology
  

1. Multistep velocity control, up to ten steps during shooting.

2. Real time control cycle -1ms.

3. High precision measurement of the possion, velocity, force of the cylinder values and real-time feedback close loop control.

4. Uniform acceleration function

• Braking At The End Of The High Speed Funtion
  

1. Improve casting product quality eftetively.

2. Reduce the gas hole ratio effetively of die casting parts.

3. Start without impact, accurately multistep velocity control, the uniform accleration function can improve die cast product surface quality and reduce the air hole ratio.

4. Non-flash technology.

5. Braking at the end of the high speed funtion, quick reply of reduce pressure & speed, avoid the impact & flash, prolong die tool life.

• Steadly Reliably Repeatablity

1. Repeated accurncy of the shooting velocity ≦2%.

2. The injection curve is stored and compared according to 100 groups of cycles. Product detection alarm.

3. High stability to ensure consistent product quality.

HOW DOES A HORIZONTAL COLD CHAMBER DIE-CAST MACHINE WORK?

Horizontal Cold Chamber High Pressure Die Casting Machine has two working methods: Maunual Operation and Full Auto Operation:

1. Manual high pressure cold chamber die casting machinery:

   The manual operation involve two key machines: Horizontal cold chamber die-cast machine and Melting furance.

   -Horizontal high pressure die caster can be choose standard type or servo driven type.

   
   

   -Melting furance: Electric melting furnace, Gas melting furance, Biological particales melting furance.

   
   

   (For magnesium alloy die casting, special Magnesium alloy automatic pouring melting furance must be used.)

   
   

   Die casting machine melting pot types:

   Graphite crucible for die casting machine melting kettle, it is popular in die casting process now.

   Cast iron crucibe for pressure die-cast machine melting pot.

   What is the Cold chamber die casting machine process

2. Full Automation horizontal cold chamber die-casting machines:

Automation equipment makes the die casting process full automatically.

The whole automatic die casting unit involve：Melting furance, Auto lading robot, Die casting machine, Auto sprayer,  Extractor.

How to choose suitable cold chamber die casting machine?

1.As per different die casting metal alloy, die caster types: aluminum die casting machine, zinc (zamak) die casting machine, magneisum die casting machine, copper (brass) die casting machine.

- Aluminum die casting machine used to produce aluminum alloy die casting parts. Use a gas or electric melting furance can start the production. Die casting mould normally is H13 mold steel.

- Zinc/Zamak die casting machine, in cold chamber types, it used to produce big zinc alloy die casting parts. (For small die casting parts, such as zipper slider, jewelry, electronic part, hot chamber die casting machine is more suitable.) Same as Aluminum die casting, just has an extra melting pot can start produce zamak die casting parts.

- Magnesium die casting machine. Magnesium alloy characters strong, light weight, easy for machining. It is more popular those years. To produce magnesium die casting part, specail ordered magnesium die casting machine with a magneisum alloy melting furance must be used. The furance connect with protect gas, avoid buring in melting process, quantitative feeding magnesium alloy to pressure machine cold chamber.

2. As per die casting machine tonnage, it can be classifed as: small die casting machine, large scale die casting mahcine.

Small die casting machine most is hot chamber high pressure injection machine. It has horizontal type and vertical type.

Large scale die casting machine normally is cold chamber pressure die-cast machine. Most is horizontal type.
