this is a plasticizing system that is specifically designed for pet molding. to fulfill the high demand for top-quality plasticizing and preform molding, it is equipped with a pet special screw with a longer l/d ratio and hard chrome coating, free on deposit material, easy to clean, with a powerful ejector force and extended ejector stroke.
besides the strong points of our standard machines, our pet machine has other advantages to ensure pet molding product with first-class quality.
1. large screw diameter and l/d ratio
2. excellent plasticizing capability
3. above-standard distance between tie bars, mold opening stroke, mold thickness and ejector stroke
4. injection unit can be designed for pet with glass fibre as an optional feature.
5. at least 4-stage pid temperature control on barrel

optional features
our service aim -“what you want is what we do”- is fully realized in our menu of optional features. optional features provide a kind of tailor made service for customers to guarantee satisfaction of their special requirements. fast response and short production time in providing this service sets us apart from our competitors in the injection molding industry. many special features can be installed per customer request. below are just some of them with brief descriptions.
1. enhanced power system (v pump system)
by using a bigger motor and hydraulic pump to increase injection speed, we can increase plasticizing speed and hence shorten production cycle times. this optional feature is suitable for thin wall molding.
2. injection with accumulator
besides enlarging the oil pump, high injection speed can also be achieved by using an accumulator. the advantages of fast response and energy saving make it suitable for molding product when there is high demand for high injection speed and long holding pressure.
3. injection on-fly, ejection on-fly
to shorten cycle times, on-fly action such as mold opening with plasticizing / ejection can be achieved by using two or more pump systems.
4. plasticizing motor that is lower by one grade
specific to any material with a low melting point, low viscosity, and good flow, a plasticizing motor that is lower by one grade can result in faster screw rotation and plasticizing speed.
increase volume
1. enlarge mold thickness
keep clamping and opening stroke unchanged, a thicker mold can be installed
2. increase injection volume
for improved economy, injection volume can be increased by extending the injection stroke within limits instead of making the injection unit higher by one grade.
3. broaden machine door
for installing molds with hydraulic cylinder(s) for core pulling, machine doors can be broadened as per customer request.
4. modular combination
for the customer who wants a machine with high injection volume but small clamping force or vice versa, all these can be achieved by different injection / clamping unit combinations.
for molding requirements, the followings features can be added
1. hydraulic core pull, unscrewing, air blow
2. power guard (pneumatic / electric), robot interface, gas-assist interface, cooling water manifold etc.
