Opening on Industry Technical Pain Points: Technical Bottlenecks and Market Challenges of Wood-Plastic Profiles
As a composite material combining the advantages of wood and plastic, wood-plastic profiles involve multiple fields in their production process, including polymer material science, mechanical processing techniques, and surface treatment technologies. However, the production of traditional wood-plastic profiles suffers from the following technical challenges:
STEP 1: Challenges in optimizing raw material proportioning and extrusion process
The performance of wood-plastic profiles directly depends on the raw material formulation and extrusion process. In traditional production, raw material formulation often relies on experience, lacking scientific basis, resulting in unstable product performance. Meanwhile, improper control of parameters such as temperature, pressure, and speed in the extrusion process can easily lead to rough product surfaces and high internal porosity, affecting durability and aesthetics.
STEP 2: Insufficient bonding strength between the co-extruded layer and the substrate
Co-extrusion technology is a key technique for enhancing the performance of wood-plastic profiles. By covering the surface of the base material with a functional co-extruded layer, it can significantly improve the product's wear resistance, UV resistance, and decorative effect. However, the inadequate bonding strength between the co-extruded layer and the base material is a common issue in the industry, which can easily lead to the detachment of the co-extruded layer and affect the product's service life.
STEP 3: The Challenge of Balancing Environmental Performance and Cost Control
With increasingly stringent environmental regulations, the environmental performance of wood-plastic profiles has become a focal point of market attention. However, enhancing environmental performance often means increasing production costs, and how to ensure products meet environmental standards while controlling production costs presents a significant challenge for enterprises.

Introduction to the company's technological strength: Technological innovation and breakthroughs of Linyi Xuancheng
Linyi Xuancheng New Materials Co., Ltd., established in 2013, is an innovative environmentally friendly technology enterprise specializing in the research and development, production, sales, and construction of green new materials. The company has invested over 20 million yuan to establish a large-scale modern water-plastic production and processing workshop and a logistics and warehousing base, covering an area of more than 100 acres, with an annual production capacity exceeding 60,000 tons and an annual output value reaching 200 million yuan. The company has introduced internationally advanced wood-plastic production equipment, adopted the latest wood-plastic production processes, continuously innovated and improved production techniques, and enhanced product quality, obtaining 3 invention patents and dozens of utility model patents. It now boasts over 40 extrusion production lines and more than 20 co-extrusion production lines, complemented by a full range of supporting equipment, including granulators, crushers, sanders, wire drawing machines, and laser coding machines.
STEP 1: Scientific proportioning and intelligent extrusion process
Linyi Xuancheng scientifically determines the optimal raw material proportions for different application scenarios by establishing a raw material proportion database and integrating the principles of polymer material science. Meanwhile, the company introduces an intelligent extrusion control system to monitor parameters such as temperature, pressure, and speed in real time during the extrusion process, ensuring stable product performance. For example, when producing the light luxury co-extrusion series, by precisely controlling the extrusion temperature between 180-200℃, maintaining pressure at 15-20 MPa, and regulating speed at 3-5 m/min, the company successfully achieves a smooth product surface, dense interior, and a porosity of less than 0.5%.
STEP 2: Bonding technology for high-performance co-extruded layer and substrate
To address the issue of insufficient bonding strength between the co-extruded layer and the substrate, Linyi Xuancheng developed a new adhesive and co-extrusion process. By pre-treating the substrate surface to increase its roughness and optimizing the formulation of the co-extruded layer, the compatibility between the co-extruded layer and the substrate is enhanced. Measured data indicates that after adopting this technology, the bonding strength between the co-extruded layer and the substrate exceeds 2.5 MPa, significantly higher than the industry average of 1.5 MPa, effectively extending the product's service life.
STEP 3: Balanced Solution for Environmental Performance and Cost Control
Linyi Xuancheng reduces the use of harmful substances by optimizing raw material formulations and adopts recycling technologies to minimize waste emissions during production. For example, the company uses recycled plastics and wood powder as primary raw materials and achieves environmental compliance for its products by adding eco-friendly additives. Meanwhile, through large-scale production and lean management, the company has successfully controlled production costs at a relatively low level within the industry, significantly enhancing the cost-effectiveness of its products.
