Second-hand PET Strapping Production Line

As a professional Chinese manufacturer deeply engaged in the plastics machinery field, Qingdao Shende is fully aware of the technical difficulties of PET strapping production. To address the common mixing issues with 1000-3000 mixers, the R&D team has optimized the equipment's performance. The mixer utilizes a double-helix stirring design with precisely calculated blade angles, ensuring uniform mixing of different raw materials within 10-15 minutes. This ensures consistent composition of the strapping materials and avoids strength fluctuations caused by uneven mixing. Equipped with an intelligent variable-frequency motor, the motor precisely adjusts the speed based on the raw material characteristics, seamlessly switching from low-speed to high-speed mixing, reducing material splashing and waste and improving mixing efficiency by over 30%. These detailed improvements, reflecting China's intelligent manufacturing, ensure that the mixing system performance of the used production line is on par with that of new equipment.

The quality of used equipment, a major concern for customers, is strictly controlled at Qingdao Shende. Every recycled PET strapping line (including 1000-3000 mixers) undergoes a rigorous process of "full-process quality inspection and core component renewal." Technicians use specialized instruments to test the mixer's mixing accuracy and speed stability, ensuring a mixing error of no more than ±2%. After disassembling the mixer, worn impellers, bearings, and other key components are replaced, using only genuine, standard parts. The entire line undergoes a coordinated test, producing PET strapping for 72 hours straight, testing its breaking strength, elongation, and other indicators. Only those that meet these standards are delivered. This process ensures that the strapping produced on this second-hand line fully meets the high-strength requirements of logistics, packaging, and other fields.

Stable performance is the core advantage of this second-hand line and the key to alleviating customer production anxiety. The 1000-3000 mixer's mixing system is precisely calibrated, allowing continuous operation for eight hours with a stirring speed fluctuation of no more than 5 rpm, maintaining a consistently high mixing uniformity of over 95%. The production line's pulling and stretching equipment utilizes synchronized drive technology, ensuring a strapping thickness tolerance of ±0.05mm, preventing breakage due to dimensional variability. After a packaging materials company adopted this system to produce PET strapping, the equipment failure rate dropped from five to less than one per month, increasing production efficiency by 25% and reducing customer complaints to zero.

When it comes to customer concerns about cost, a used production line offers significant advantages. While a new PET strapping line (including a 1000-3000 mixer) can cost hundreds of thousands of yuan, Qingdao Shende's used line offers a 60% reduction, enabling production for just over a hundred thousand yuan. A small strapping factory in Zhejiang province used this purchase to invest in new, environmentally friendly raw materials. The resulting strapping, with its exceptional weather resistance, quickly gained popularity in the export market, earning back its investment in the equipment in just six months.

Qingdao Shende's used PET strapping production line (equipped with 1000-3000 rpm mixers) leverages the technical expertise of a professional Chinese manufacturer to address customer pain points such as uneven mixing, unstable equipment, and high investment costs. Choosing this line allows businesses to achieve stable production at low costs while securing market share with high-quality strapping, helping them gain a firm foothold in the packaging materials industry.
