When a set of our extrusion blow molding machines departed from the factory and headed to a plastic packaging manufacturer overseas, a special mission also kicked off. Our senior engineer, Chris, embarked on a 10-day overseas journey, shouldering the responsibility of equipment installation, commissioning, and technical training. His trip was not only about delivering professional after-sales service but also about building a solid bridge of trust with our overseas customers.
Upon arriving at the customer's factory, Chris immediately threw himself into work without any rest. The first task was to conduct a comprehensive inspection of the equipment. He carefully checked every component of the extrusion blow molding machine, from the extruder and mold clamping system to the hydraulic and electrical control units, ensuring that all parts were intact after long-distance transportation. "The local climate here is a big test for the equipment. Extreme temperature and humidity may affect the performance of electrical components and hydraulic oil. I must be extra careful," Chris explained while recording data with a notebook.
The installation process required extreme precision. Chris worked closely with the customer's on-site team to hoist and position the machine accurately. He adjusted the levelness of the equipment base repeatedly, calibrated the alignment between the extruder and the mold, and strictly followed the installation manual to connect the water, electricity, and gas pipelines. During this period, he encountered a small challenge: the customer's factory had slightly different voltage parameters from the standard configuration of the machine. To solve this problem, Chris promptly adjusted the electrical control system and replaced some matching components, ensuring that the machine could adapt to the local power supply environment perfectly. This quick response won unanimous praise from the customer's technical director. "We were worried about the voltage issue before, but you solved it in just a few hours. Your professionalism is impressive," he said.

After the installation was completed, the most critical commissioning phase began. The extrusion blow molding machine is mainly used to produce plastic bottles for edible oil, and the customer has high requirements for the thickness uniformity and surface smoothness of the bottle walls. The engineers first set the relevant parameters according to the customer's product specifications, including the extrusion speed, mold temperature, blowing pressure, and cooling time. Then, they started the test run. With the hum of the machine, the first batch of plastic bottle blanks was successfully extruded and blown into shape. After careful inspection, the product parameters fully met the customer's requirements. Subsequently, the engineers conducted continuous test runs for 24 hours, monitoring the machine's operation status in real-time and optimizing parameters to improve production efficiency. Finally, the machine achieved a stable production capacity of 800 bottles per hour, which was 10% higher than the customer's expected target.
Technical training is an important part of the after-sales service. Chris tailored a detailed training plan for the customer's operators and maintenance personnel. He explained the working principle, operation process, and daily maintenance points of the extrusion blow molding machine in detail, using both theoretical explanations and on-site demonstrations. During the training, the customer's staff raised many questions, such as how to deal with mold blockages and how to adjust parameters for different types of plastic materials. Chris patiently answered each question and guided them to practice hands-on. "I not only want to deliver high-quality machines to customers but also let them master the skills to use and maintain the machines proficiently," Chris said. After the training, the customer's operators could independently complete the entire production process, and the maintenance personnel were able to handle common faults.
During the stay, Chris also had in-depth communication with the customer about future cooperation. The customer expressed great satisfaction with the performance of the extrusion blow molding machine and our professional after-sales service, and indicated that they planned to purchase two more sets of machines next year to expand production capacity. In addition, they put forward some suggestions for product improvement based on their actual production needs, such as adding an automatic material feeding system. Chris carefully recorded these suggestions and said he would feedback them to the R&D team to optimize the product.
When the mission was completed and Chris was about to leave, the customer's technical director held a farewell dinner for him. He said, "Your extrusion blow molding machines are of reliable quality, and your after-sales service is timely and professional. This cooperation has made us more confident in expanding the market. We look forward to working with you for a long time."
This overseas mission is a microcosm of our company's commitment to "quality first, service-oriented". For us, selling extrusion blow molding machines is not the end of cooperation, but the beginning of a long-term partnership. We will continue to provide professional technical support and thoughtful after-sales service for global customers, helping them achieve better development in the plastic processing industry. Engineers like Chris will continue to spread their footsteps across the world, bringing high-quality Chinese manufacturing and professional services to more countries and regions.
