Automatic Blow Molding Equipment

Servo systems' response time is 60% shorter than that of ordinary motors, and it can remain stable during high-speed production (such as 2000 bottles/hour). The fast start-stop feature is particularly suitable for stretch blow molding processes that require frequent speed changes, effectively shortening the molding cycle by about 15%. The servo system consumes energy only when needed, saving 30% to 50% of energy compared to asynchronous motors. Under continuous production conditions, each device can save up to 8000-12000 kWh of electricity per year, significantly reducing production costs.

Airtac's mold-jointing rails adopt a combination design of linear guides and precision ball screws, with a repeat positioning accuracy of up to ±0.02mm, which is significantly better than traditional hydraulic mold-jointing systems. This accuracy ensures that PET bottle preforms can be perfectly centered at high temperatures, avoiding defects such as eccentric bottle mouths and uneven wall thickness. Actual measured data shows that the qualified rate of bottle blowing machines using this system can be increased to more than 99.9%.
