What is bottle-preform making machine?

It is an machine system which used to produce pet preform. The preform is used to blowing plastic water-bottle.

The preform making machine is used to shape liquid plastic into solids. It is generally classified as hydraulic plastic injection machine, and mechanical plastic injection machine.

Capacity of production2300 psc depend on 18gram preform
Injection Ton100 ton
Mold cavity4 Cavity

Advantages of the injection molding machine

1. The preform making machine is equipped with double mold adjusting motors, which ensures steady and smooth operation of mold adjusting.
2. It is designed with optimum oblique ranked five-points supporting curved rib and cabinet-type mold.
3. The movable mold board makes use of self-regulating support, which protects draw bar and also extend its life time. Meanwhile, it renders smooth and steady mold locking.
4. The double injection-advancing hydro-cylinders guarantee the injection process is steady and smooth and no deformation for fixed mold board.
5. The hydraulic system adopts pressure-flow double-scaling to control oil channels. In addition, the machines make full use of international famous brand hydraulic elements, and are accompanied with reasonable oil lines to ensure smooth and steady running of the machine.
6. Double-cylinder balanced injection, screw rods, material tubes, non-step, large-torque hydraulic motor, adjustable speed control and adjustable back pressure, combine to meet requirements of the various plastic to be injected and shaped.

Well-distribute Heated Wind The heat efficiency is high enough to shorten great amount of drying time. Precise Temperature Controls The precise temperature controls ensure and keep a high accuracy of temperature. Save Time and Manpower As the hopper body and bottom are designed separately, and therefore it is very convenient to clean materials and quite simple and quick to renew materials as well. The Trustworthy Design Fine exterior,solid construction.Short material-melting time greatly helps to promote the spouting speed.

3. Auto Loader

The main engine and the material hopper are designed separately,and thus it is safe,easy and convenient to be opperated.

The whole operation is controlled by MicroTrip computer.

Equipped with an independent filter,which is very convenient to clean up dust.

The equipped muffler reduces the noise in operation.

Stainless steel material hopper is light in weight,durable and very convenient for cleaning the device.

The control box,being designed separately,is easy to be well maintained.

Auto-buzzer will give alarm while lacking material.

Auto-protective device protects motor against overloading.

4. Preform Mold

Preform tensile tests using computer simulation designed to ensure blowing success rate.

  • Using the world forward two double taper positioning technology, each cavity independent self-locking, concentricity ≤ 0.08mm.
  • The mold cavity, core selection Sweden and Germany imported mirror plastic mold steel corrosion resistance, high hardness, long life.
  • Threaded ports according to international standards, imported nitrided steel, high hardness, long life.
  • Runner advanced design, single-point nozzle temperature, heating temperature, improve the quality of preform.
  • Excellent cold room temperature water cooling system to achieve high efficiency, fully automated production.
  • Free scissors gate, ensuring automatic production mold, reduce workers’ labor.
  • Mould life of at least 300 million times die times.
  • Runner using PID control system, which is characterized by automatic repair and automatic protection function, prolong the service life of electric devices;
  • Temperature control within 1 degree, sure to avoid being burned material within the hot runner is occurring, can yield more than 99%;
  • New nozzle design makes it easier to mold maintenance, parts ejector nozzle, heating parts, insulated part, and the thermocouple without removing the case easy to replace mold, helps to reduce downtime and saving maintenance costs.

The plastic injection machines used to produce various plastic are with variable sizes, from tiny to extremely large machines, depending upon end products.

That plastic injection machines are so popular is partly owing to the simple structure, ease of use, and competitive prices. The plastic injection machine has only a small number of major parts, including hopper, barrel, heater, a plunge needle, a casing unit, and an ejection device. Sizes and types of these parts vary according to the materials to be molded.
