We firmly believe that partnership is more than just a transaction; it’s a long-term commitment. This belief prompted Chaoxin Machinery Technology’s after-sales service team to recently travel to Saudi Arabia to fulfill a scheduled maintenance appointment for a valued, long-standing customer. This trip vividly demonstrated our expertise, problem-solving skills, and human warmth that transcends borders.
Upon arrival at the customer’s factory, we discovered that the blown film machine, which had been operating continuously for several months, was showing signs of wear. The core issue was persistent leakage and a slight decrease in production efficiency, which was causing significant distress to the customer’s production team.
For any blown film manufacturer, leakage is a critical issue, resulting in material waste, production downtime, and inconsistent product quality. Our mission was clear: not only to repair the machine, but also to thoroughly eliminate the root cause of the leakage.

A Two-Pronged Approach: Repair and Training
Our certified technical engineers immediately conducted a comprehensive inspection of the entire production line, from the screw and die head to the traction system.
1. Precision Maintenance: We methodically disassembled, cleaned, and replaced worn parts. The key was recalibrating the die gap—after long-term operation, the die had developed micron-level deviations, which were the primary cause of material leakage. We also checked and stabilized the heating temperature to ensure optimal melt flow.
2. Empowering the Team: Noticing that the customer’s team included new operators, we went beyond simple instructional instruction and provided hands-on, on-site training at the machine, focusing on:
Correct parameter settings and raw material ratios;
Tension control and film thickness adjustment during operation;
Most importantly, we demonstrated step-by-step how to prevent material leakage: how to use a feeler gauge to calibrate the die gap, how to identify temperature sensor failures, and tips for daily material screening.
“So the leakage was caused by a tiny misalignment of the die gap! Now I understand!” exclaimed the customer’s production manager. After applying our methods, machine operation quickly stabilized, the leakage problem disappeared, and film quality improved significantly.
Just as the maintenance work was nearing completion, a minor incident occurred: one of our technical engineers suffered a minor scratch on his hand. At that moment, our relationship evolved from a simple customer-supplier relationship to a true partnership.
The client’s representative personally provided first aid, immediately arranged for a vehicle to take the engineer to the clinic for a tetanus shot, and even proactively upgraded our team’s accommodations to ensure their comfortable recovery. This sincere care deeply demonstrated that our partnership is built on mutual respect and compassion.
When we returned to China, we brought back not only a fully repaired machine but also a deepened friendship. The client wrote a handwritten thank-you letter and gave us a five-star review on a B2B platform, praising our “professional technology and attentive service.”
