production line
The production process of PP (polypropylene) boards mainly includes 5 core steps:
Raw Material Preparation: Mix PP resin (main material) with additives (e.g., anti-aging agents, flame retardants) in a mixer to ensure uniform blending.
Melting & Extrusion: Feed the mixed materials into an extruder. The extruder heats (at 180-220℃) to melt the materials, then pushes the molten PP through a die to form a continuous sheet.
Calendering & Shaping: Pass the molten sheet through a set of calender rolls. The rolls (controlled for temperature and pressure) flatten and smooth the sheet to the target thickness.
Cooling & Cutting: Cool the shaped sheet with water or air to solidify it. Then, use a cutting machine to trim it into standard-sized boards or custom dimensions.
Quality Inspection: Check the boards for thickness uniformity, surface defects (e.g., scratches), and mechanical properties (e.g., impact resistance) before packaging and storage.
oem/odm
The OEM (Original Equipment Manufacturer) model for PP plastic plates has become a preferred cooperation method for many enterprises due to its flexible adaptability and resource integration capabilities, with core advantages focusing on the following four aspects:
1. Precisely meeting personalized needs for diverse application scenarios
PP plastic plates are used in multiple fields such as chemical industry, construction, and food industry, where requirements for plate specifications (thickness, size), performance (flame retardant grade, acid and alkali resistance), and appearance (color, surface texture) vary significantly. The OEM model enables customized production according to customer needs, eliminating the need for customers to adjust production lines themselves and achieving the flexibility of "customization on demand".
2. Lowering production entry barriers and reducing enterprise operating costs
The production of PP plastic plates requires investment in professional equipment such as extruders, calendering equipment, and cutting units, as well as a technical team to control key parameters like melting temperature (180-220℃) and calendering pressure, resulting in high initial fixed asset investment and later maintenance costs. By choosing the OEM model, customers do not need to purchase production equipment or build a technical team. They can focus funds and energy on core businesses (e.g., product design, marketing) and reduce unit production costs through bulk OEM, avoiding resource waste caused by equipment idleness and production capacity loss.
3. Ensuring stable product quality with professional production experience
Formal PP plate OEM manufacturers have mature production processes (e.g., raw material proportioning, melt extrusion, quality inspection) and rich technical accumulation to strictly control product quality. On one hand, they ensure the performance of PP plates meets standards by accurately controlling the proportion of additives (anti-aging agents, flame retardants); on the other hand, they reduce product defect rates through standardized quality inspection links (thickness uniformity check, surface defect screening, impact performance test). Compared with in-house production, the OEM model can more stably produce PP plates that meet industry standards or specific customer requirements, reducing quality risks.
4. Shortening production cycles and improving market response efficiency
When customers face urgent orders or fluctuating market demand, OEM manufacturers can quickly adjust production capacity relying on large-scale production capabilities and mature supply chain systems. Meanwhile, the OEM model supports small-batch trial production, facilitating customers to quickly verify market feedback on products and adjust specifications or performance in a timely manner, thus improving the response speed to market changes.
R&D
1. Innovation in Environmental Protection and Sustainability
Centering on "full-lifecycle environmental protection", the raw material sector focuses on the recycling and modification of PP waste (e.g., industrialization of glass fiber-reinforced recycled PP). The process sector has made breakthroughs in formaldehyde-free technology (e.g., "paperless direct lamination technology" to eliminate formaldehyde). Meanwhile, the utilization of solid waste as resources is further deepened to reduce raw material consumption and carbon emissions.
2. High-Performance Modification and Functional Upgrading
To address the shortcomings of traditional PP plates, basic performance is enhanced through transparent modification (three technical routes) and high melt strength modification (HMSPP). At the same time, functional compounding is promoted—for example, ultra-thin PP ceramic plates achieve weight reduction and bendability while maintaining core performance, expanding high-end application scenarios.
3. Process Innovation and Scenario Adaptation Optimization
Molding processes (microporous technology) and finishing processes (integrated "paperless direct lamination") are continuously innovated. Meanwhile, customized production lines are optimized to flexibly adjust the thickness, texture, and functional properties of plates, adapting to the needs of diverse fields.
4. Expansion of Application Scenarios and Form Innovation
Relying on technological breakthroughs, cross-field penetration is achieved in construction (thin plates), new energy (microporous membrane PP plates), and medical care (antibacterial transparent PP plates). At the same time, form innovation (mass production of large-sized plates) is promoted to support new application models and improve construction efficiency.
