HD Series Three platen injection molding machine

About WIA----Established in 1994, Guangdong WIA Precision Machinery Co.,Ltd. is one of the largest and most professional manufacturers of high-precision plastic injection molding machines in China.
Through decades’ years of research and design, we have made numerous technical breakthroughs and our products have won praise from customers around the world, many of whom have become our distributors. Our fully hydraulic four-cylinder structure has been awarded the patent by the government of China, the USA, Japan and many European countries.
In 2003, we developed the first Chinese digital disc injection molding machine. This is a milestone of China’s plastic injection molding machine industry because never has any Chinese manufacturer made a disc injection molding machine before. Our repeatable accuracy of the final product is up to 0.14% and our injection speed is up to 1000mm/s and we are the best choice for worldwide customers to produce high-precision products such as digital discs, light-guide boards and electronic components. Our machine could make light guide board at 0.4mm thickness. And our hydraulic system is highly tidy and clean and most suitable for food packing and medical appliance production.


The long opening stroke allows the machine to load bigger thickness mold, and is especially ideal for those products which require extra long opening stroke for its production.
The four clamping cylinders enable even stress of tie bar and thus prolonging its life time as well as compensating the default of uneven dimension of the mold, the life time of mold will be prolonged also.
Twin mold opening cylinders ensure the mold closing and the mold opening fast and stable, provide distinguished low pressure mold protection function.
With the two-platen design the length of the machine is reduced by 20% comparing with the same size three-platen machine, relative space occupied can also be saved by 20-25%.
Adoption of multi-combination variable displacement pump the effect of power savings is achieved, because power is consumed only when each and every movement of the machine is performed.
Fast and convenient mold change, no mold adjustment procedure is required.

Clamping system
The length of the machine is reduced by 20% comparing with the same size three platen machine, relative space occupied can also be saved by 20-25%
Being optimized by finite element analysis, the even stress distribution on the platen minimizes the chance of deformation while can prolong its life time also
The four clamping cylinders enable even force distribution of tie bar and thus prolonging its life time as well as compensating the default of uneven dimension of the mold, the life time of mold will be prolonged also
The precision clamping ensure good quality of the product, “ sprue sticking” of the product is being prevented
As the mold adjustment is not required on the two platen machine, the mold change procedure is simplified.
Twin mold opening cylinders ensures fast and stable mold close and mold open, provide distinguished low pressure mold protection function.
Sliding support under the moving platen allows loading of more heavy mold weight and unsures the precision position of the mold during mold closing .
Can dispense with the maintenance work of the toggle parts which wear by long time and frequent strong stress.
Electrical safety doors for more speedy and stable door movement.


Injection system
Strong construction of twin injection cylinder ensures reliable and stable injection
Twin carriage cylinders ensures even stress of injection unit during injection and prevent the default of drooling
Optimized design of nitride screw and anti-abrasive screw head, check ring and seat realizes better plasticizing effect.
Regld injection mechanism ensure stable injection

Hydraulic system
Close-loop control realized by the application of imported close loop variable displacement multi-pumps from Japan &Europe enabling high precision and energy savings of machine operation
Optimized hydraulic circuit design realizes speedy and stable movement with distinguished mold protection function
The adoption of imported pressure sensor ensurs more precision pressure detection
The adoption of imported will known brand of directional valve and cartridge valve minimizes the leakage of hydraulic circuit
Automatic self ludrication system enables more easy and speedy machine maintenance
