Linear Variable Pitch PET Blow Moulding Machine with Continuous Heating

Company Introduction

Yawei Machinery specializes in manufacturing two–step high speed fully automatic linear PET blow molding machine for water,juice,soda,carbonated drinks, edible oil, food, pesticide,pharmaceutical and cosmetics,etc. With more than 20 years experience in developing and producing water bottle blow molding machine, we have developed, with our constant innovation, dozens of high speed PET blow moulding machines which have won great reputation in the filed.

Technology innovation is our eternal tenet. Continuous improvement and genuine professionalization are what we have been chasing while extreme precision, stability, higher bottle, high speed, quality,enery saving,and high efficiency are what we live upon. Meanwhile,we are to satisfy the customers with perfect after-sales service.Yawei Machinery will always, together with you,create a better future.

Quality Control

Rigid enterprise criteria and manufacturing processes to make superior quality.

Ø   All of our products are designed with 3D and 2D softwares.

Ø   Major parts are all processed with CNC lathes and machining centers and then fitted and assembled to ensure the accuracy of fitting.

Ø   Most of the components and accessories are of famous brands.

Ø   Each machine must be subjected to 80~100hrs uninterrupted operation test before delivery.

The normative quality monitor system plays a key role for Yawei PET stretch blow molding machine to satisfy customers and occupy a position in the market. We have established the data analysis and tracking system for those critical parts and components, such as the electrical, mechanical parts,pneumatic components, servo motors and so on. Producing high quality PET blow molding machine machines has been the primary working principle of every staff of Yawei Machinery

Preform Stepping System

Servo motor-driven preform stepping makes it much speedy and stable,and shortens the production cycle time, greatly improve production efficiency.And our special  design can perfectly solve the preform-blocked and preform abrasion problem.

Heating System

This machine uses servo motor for precise rotary heating system. The preforms (neck up) rotate 360 degrees continuously while heated in the oven with paratactic collocation, allowing more preforms to be heated in the same space. This boosts efficiency and saves over 60% in energy. The preform transfer system ensures high-speed, accurate handling and thorough & even preform heating.Bottles are easier to be shaped, and the finished bottle appearance and thickness uniformity are better,especially for the extremely low and extremely high gram weight of bottle without any strengthening ribs

Preform Lifting System

The preform lifting servo motor avoids air turbulence, improving both stability and speed,compared with traditional air preform lifting system

Pitch Change System

This mechanism changes pitch distance with a servo motor, to ensure high speed and accurate preform handling.Our special pitch change system is characterized by higher stability,less power consumption,longer lifespan and easier maintenance.

Clamping System

 The mold clamping mechanism:two servo motors are adopted to fulfill the reciprocating up and down of the two hinge mechanisms on both sides of the mold. The servo motor driven mold movement mechanism is designed and created upon rigid engineering simulation analysis,balanced force,faster,higher precision,longer lifespan,which ensures mold motions are simple, accurate, consistent and speedy, with cycle time 0.3~0.5 seconds.

Stretching System

The stretching rods are driven by a servo motor all at once, which ensures the synchronicity of the rods motion and makes it easier to do adjustment prior to production. Servo motor driven stretching system (Down stretching and blowing), more conducive to the forming of the bottle bottom, bottle blowing effect is better．
