The Guanshentai Automatic Pipette Stretching and Molding Machine is specialized equipment designed for the automated stretching and forming of tubular consumables such as plastic pipettes, Pasteur pipettes, and droppers. Integrating automatic tube blank feeding, zoned heating and softening, servo-driven stretching, fixed-length tip cutting, cooling/setting, and automatic unloading, the machine enables a one-stop automated production process from plastic tube blanks to finished pipettes. It achieves production speeds of 600–1,200 units per hour (depending on specifications) and is compatible with various thermoplastic materials, including PP, PE, PS, and PETG.
Technical parameters:
Equipment model: GST-YYG102A
Pipette capacity: 1-10ml (1 device can only process a pipette of one capacity)
Production efficiency: 3000-3600 pieces/hour
Equipment size: length 160 * width 100 * height 170cm
Equipment weight: about 750KG
Power (Output): 3KW
Customized Support: Yes
Key Advantages:
Uniform Zoned Heating: Utilizes a multi-zone independent temperature control system to ensure even heating and consistent softening of the tube blank. This prevents localized overheating—which could cause material carbonization or rupture during stretching—thereby ensuring the transparency and toughness of the molded pipette body.
Precision Servo Stretching: Employs a servo-motor-driven stretching mechanism allowing for precise control of stretching speed and ratios. The resulting pipettes feature uniform diameters and consistent wall thickness, with smooth, burr-free tips and clean, string-free cut ends.
Precision Fixed-Length Cutting: Equipped with a servo-controlled fixed-length cutting system, the machine allows for adjustable cutting lengths with precision controlled to within ±0.5 mm. The cut edges are smooth and clean, eliminating the need for secondary trimming.
Rapid Specification Switching: By changing heating molds, stretching clamps, and cutting dies, the machine can quickly adapt to various pipette specifications ranging from 0.1 ml to 10 ml (tube lengths of 50–300 mm and diameters of 3–15 mm), offering flexible and convenient production changeovers.
Clean and Safe Design: The machine features an enclosed protective structure that isolates the heating zone from drive components. It is equipped with emergency stop functions and safety light curtains to ensure operator safety and is suitable for use in cleanroom production environments.
Applications:Widely applicable to the automated stretch-forming of tubular consumables in sectors such as life science consumables (disposable pipettes, Pasteur pipettes, serological pipettes, droppers), medical consumables (medication and sample droppers), and laboratory equipment. With its high efficiency, precision, and stable forming performance, the Guanshentai automatic pipette stretch-forming machine helps manufacturers of laboratory consumables upgrade their tube-forming processes to automation, effectively boosting production capacity and product quality consistency.
