Raw material incoming inspection

We strictly implement source quality control, and all raw materials entering the factory must pass professional testing. Metal materials are analyzed using a German imported spectrometer for composition, and key mechanical components are measured using a coordinate measuring instrument to ensure dimensional accuracy of 0.005mm.

Production quality monitoring

In the production and manufacturing process, we implement full process quality tracking. 100% full inspection system is implemented for the processing of key components, and the deviation of spindle dynamic balance is controlled within 0.01mm. Establish complete quality records for each production process to achieve full traceability.

Whole machine inspection standard

Each device must undergo a comprehensive test of 120 hours before leaving the factory. Including 48 hours of no-load operation test for the accuracy of each axis motion, and 72 hours of full load production verification for stability. Ensure the safety and reliability of the equipment.

Customer on-site service guarantee

We provide professional on-site installation and debugging services, use customer specified raw materials for 24-hour continuous production verification during acceptance, and complete operator training. Establish lifelong equipment records to provide customers with continuous quality assurance.

What types of blow film machines do you offer?

We offer:

Single Screw Extruder Blow Film Machine: Suitable for basic PE, LDPE, HDPE films.

Twin Screw Extruder Blow Film Machine: Ideal for recycled materials and high-filled films.

High-Speed Blow Film Machine: Increases production capacity, stable operation.

Multi-Layer Co-Extrusion Blow Film Machine: Suitable for multi-layer composite and functional films.

What is the production capacity and speed of your machines?

Depending on the model and material configuration, the production capacity ranges from 50kg/h to 300kg/h, with film width ranging from 50mm to 2000mm, and capable of high-speed operation.

Can recycled or filled materials be used?

Yes, especially with the twin screw extruder machines, which are designed to handle recycled materials and high-filled resins, reducing production costs.

What is the failure rate of the equipment running continuously for 30 days?

Under standard operating and maintenance conditions, the failure rate for 30 consecutive days is less than 1%.

Is special configuration required for PLA/PBAT material production?

Yes. For PLA/PBAT and other degradable materials, we provide special screw, temperature control system and exhaust structure to adapt to their processing characteristics.
