- since 1985 -
In 2022, a factory in Tianjin, China purchased a second-hand air bubble film machine that was originally manufactured by HLGP machinery.
Since the machine was purchased through a third-party trader instead of directly from our company, the customer did not receive official technical support after the transaction. Shortly after the purchase, the machine encountered operational problems and failed to start, causing production delays and additional costs.
The customer tried to contact the original seller for assistance, but the trader was no longer available. With production affected, they searched for a solution and eventually found HLGP machinery through our official website.
Although they were not our direct customer, they contacted us hoping that our technical team could help restore the machine.
Normally, equipment manufacturers mainly provide after-sales service for machines purchased directly from them. However, this machine was manufactured by HLGP machinery, and we understood that its performance represented our brand reputation.
After receiving the customer's request, our engineering team arranged technical support for the Tianjin factory.
Our technicians inspected the machine operation, identified the causes of the failure, and carried out necessary adjustments, including:
After systematic troubleshooting, the second-hand bubble film machine was successfully restarted and returned to normal production.
After the repair, the machine continued operating reliably for the following years.
During this period, the customer experienced the stability of HLGP machinery equipment and our approach to technical support. Although the original machine was purchased second-hand, we continued to provide assistance whenever they needed technical guidance.
In 2026, as the customer's business continued to grow, their existing production capacity could no longer meet market demand. They decided to invest in a new high-speed automated bubble film production line and contacted HLGP machinery again.
The cooperation process was highly efficient:
Day 1:
The customer sent an inquiry regarding the new production line.
Day 2:
After technical communication and confirmation of requirements, the contract was signed and the deposit was received.
The customer chose HLGP machinery again because they had already experienced our equipment reliability and service support firsthand.

This case demonstrates that our relationship with customers does not end after equipment delivery.
Whether a customer purchases a new bubble film machine, bubble wrap production line, or operates an existing HLGP machine purchased through another channel, we always focus on helping customers maintain stable production.
At HLGP machinery, we believe that reliable equipment is not only about manufacturing quality, but also about long-term technical support throughout the machine's service life.
With more than 35 years of experience in plastic extrusion machinery manufacturing, HLGP machinery continues to provide professional solutions for customers worldwide, helping them improve production efficiency and achieve long-term business growth.
