Quality Control

Quality is the life of an enterprise

Quality control is one of the core philosophies of Zibo Treeplas New Material Technology Co., Ltd. We understand that in the fierce market competition, only exceptional quality can win the trust of customers and recognition from the market. Therefore, we implement quality control throughout all aspects of product development, production, and sales, ensuring that every shipment of plastic sheets leaving our factory meets the highest standards.

Strict incoming inspection of Raw Materials

We are well aware that high-quality products stem from high-quality raw materials. Therefore, in the procurement process, we strictly select suppliers to ensure that all raw materials meet our corporate standards. Each batch of raw materials must undergo stringent quality inspections before being stored, including visual inspections and performance tests, to ensure they meet production requirements. Additionally, we have established a comprehensive raw material traceability system that allows us to quickly identify and resolve any issues at their source should any quality problems arise.

Refined Production Process Control

In the production process, we implement refined management, strictly controlling every step from raw material input to finished product output. We have developed detailed production processes and operating standards, requiring employees to operate in strict accordance with these regulations. Additionally, we have introduced advanced production equipment and testing instruments to monitor and adjust key parameters in real-time continuously for 24 hours, conducting sampling tests every 2 hours to check for longitudinal and lateral thickness deviations, transparency, flow marks, and crystal points, among other things. This ensures the stability and consistency of all the products of PET sheet, PP sheet, PVC sheet, HIPS sheet and etc. Furthermore, we regularly maintain and service our production equipment to ensure its normal operation and efficient production.

Comprehensive Quality Inspection

To ensure the high quality of our products, we conduct comprehensive quality inspections on every batch. This includes visual inspections, dimensional measurements, performance testing, and more. We utilize advanced testing equipment and technological methods to precisely measure and evaluate various indicators of the products. Only those that pass stringent inspections are allowed to leave the factory for sale. Additionally, we have established a thorough quality record management system to document and analyze the quality data of each batch of products, enabling us to promptly identify issues and make improvements.

Continuous Improvement and Innovation

We adhere to a customer-centric approach, paying close attention to industry trends and changes in customer needs, continuously optimizing our production processes and improving product quality levels. We encourage employees to propose improvements and suggestions, driving continuous improvement in quality control through technological and management innovations. Additionally, we have established cooperative relationships with universities and research institutions to jointly develop new technologies, products, and processes, providing strong support for the sustainable development of the company.
