For mass production orders, we typically require a 40% advance payment, with the remaining balance due upon receipt of the bill of lading. While T/T (Telegraphic Transfer) is our most commonly accepted payment method, L/C (Letter of Credit) is also an acceptable option.

I. Raw Material Control

1. Strict Supplier Screening

   • Select HDPE raw material suppliers with strong reputations and quality guarantees. Suppliers must provide detailed product quality reports, including key parameters such as resin density, molecular weight distribution, and melt flow rate, ensuring compliance with production requirements. For example, high-quality HDPE suppliers utilize advanced production processes to consistently produce raw materials with a density of approximately 0.7–0.75 g/cm³, which enhances the strength and durability of the material used in furniture.

2. Raw Material Inspection

   • Each batch of raw materials is inspected upon arrival. Sampling checks are conducted to examine the resin’s appearance (e.g., color, transparency, and presence of impurities). Additives are verified for type and content compliance. For instance, spectroscopic analysis is used to detect the content of antioxidants and light stabilizers, ensuring antioxidant levels remain between 0.1%–0.5% and light stabilizers are within the appropriate range, thereby guaranteeing the furniture’s anti-aging performance.

3. Mechanical Performance Testing

   • Conduct strength and toughness tests on finished furniture. For example, universal testing machines are used to perform compression tests on seat surfaces, which must withstand at least 1000N of pressure without cracking or excessive deformation under relevant standards. Components like armrests undergo bending tests to verify their flexural strength, typically requiring a minimum of 25 MPa. Impact tests are also essential: impact testing machines simulate accidental collisions during use, ensuring impact strength remains less than 5kJ/m² (not less than 5kJ/m²).

4. Dimensional Accuracy Inspection

   • Use measuring tools (e.g., calipers, tape measures) to check furniture dimensions. Verify that the height, width, and length of tables and chairs comply with design specifications, with deviations controlled within ±5mm. For complex-shaped components, coordinate measuring machines (CMM) or other precision equipment ensure shape accuracy, surface flatness, and absence of deformations or distortions.

5. Weather Resistance Testing

   • UV resistance tests are conducted using aging chambers that simulate sunlight exposure. Furniture samples are placed in the chamber and subjected to specific UV intensity and duration. Post-test color change is measured, requiring a ΔE value ≤3 (ΔE quantifies color difference; lower values indicate less change). Temperature resistance tests involve placing samples in high-low temperature chambers cycled between -30°C and 60°C to check for softening, deformation, brittleness, or cracking. Water resistance tests include splashing or immersion to evaluate water penetration or absorption.

II. Personnel and Management

1. Employee Training

   • Provide professional training for production staff, covering operational skills and quality awareness. For example, injection molding operators are trained to set machine parameters correctly, identify quality issues, and make timely adjustments. Quality awareness training uses case studies and standards to emphasize the importance of quality, encouraging adherence to specifications during production.

2. Quality Management System

   • We are White Wood Grain Effect Round Multi-Functional Table HDPE Material with Square Storage Rack Company in China. Implement a comprehensive quality management system, such as ISO 9001. Strictly follow quality manuals and procedural documents during production. Key control points are recorded for traceability and continuous improvement. For instance, document raw material details, production parameters, and quality test results for each batch to quickly identify and address issues if quality problems arise.

III. Production Process Control

1. Injection Molding/Extrusion Processes

   • Precisely control injection molding temperature, pressure, and speed. For HDPE, the injection temperature typically ranges between 180°C–260°C, with fine-tuning based on mold and product structure. Improper pressure control can cause defects like flash or sink marks, so adjust pressure (usually 50–150MPa) according to product size and shape. Injection speed must be optimized: too fast may cause internal stress concentration, while too slow reduces efficiency.

   • For extrusion molding, control screw speed, haul-off speed, and cooling conditions. Screw speed (generally 30–60 rpm) affects material conveying and plasticization. Haul-off speed must match extrusion speed to ensure dimensional accuracy. Cooling methods (e.g., water or air cooling) and duration impact quality; uneven cooling may cause warping or deformation.

1. Injection Molding Production Lines
- Product Types and Capacity Estimation: Assuming 4 injection molding lines are dedicated to producing HDPE furniture components, such as chair seats, chair backs, and tabletops. If one injection molding line can produce 30–50 chair seats per hour (depending on size and complexity), operating 20 hours per day (accounting for equipment maintenance and mold changes), a single line can produce 600–1,000 chair seats daily. With 4 lines, the daily production capacity reaches 2,400–4,000 chair seats.
- Mold Changes and Multi-Product Production: Injection molding lines can switch molds to produce diverse products. For example, after producing a batch of chair seats, switching molds enables the production of table legs. If mold changes are completed within 2–3 hours and operators are skilled in adjusting parameters for different products, these lines can flexibly schedule the production of various furniture components weekly, further enhancing overall capacity.

2. Extrusion Production Lines
- Pipe and Profile Production Capacity: Assuming 3 extrusion lines are used to produce HDPE pipes (e.g., frames for chairs and tables) and profiles (e.g., decorative strips). One extrusion line can produce 100–150 meters of pipes or profiles per hour (varying by size), operating 20 hours daily. A single line can thus produce 2,000–3,000 meters daily. With 3 lines, the total daily output reaches 6,000–9,000 meters of pipes or profiles, which can be cut, processed, and assembled into a large quantity of furniture.
- Product Diversity and Customized Production: Extrusion lines can produce pipes and profiles of different shapes and sizes to meet customized HDPE furniture demands. as professional White Wood Grain Effect Round Multi-Functional Table HDPE Material with Square Storage Rack Suppliers in China. For instance, uniquely designed outdoor furniture may require non-standard pipe dimensions for frames. Extrusion lines can easily adjust parameters to fulfill such needs, enhancing the factory’s adaptability to diverse customer orders.

3. Assembly Production Lines
- Assembly Efficiency and Capacity: Assuming the factory has 3 assembly lines, each equipped with sufficient workers and tools to assemble components from injection molding and extrusion into finished furniture. If one assembly line can assemble 10–15 table/chair sets per hour (depending on complexity), operating 20 hours daily, a single line can assemble 200–300 sets daily. With 3 lines, the daily assembly capacity reaches 600–900 sets.
- Quality Control and Capacity Balance: Quality checks during assembly impact overall capacity. By implementing efficient inspection points to identify and address component issues promptly, rework delays can be minimized. Additionally, maintaining capacity balance across injection molding, extrusion, and assembly lines prevents bottlenecks or idle time, ensuring optimal utilization of the 12 production lines.

4. Surface Treatment Lines (If Applicable)
- Surface Treatment Methods and Capacity: Assuming 2 surface treatment lines are used for processes like spraying or sanding on HDPE furniture. If one line can process 50–80 furniture pieces per hour (depending on size and process complexity), operating 20 hours daily, a single line can process 1,000–1,600 pieces daily. With 2 lines, the daily processing capacity reaches 2,000–3,200 pieces.
- Environmental Compliance and Efficiency: Surface treatment processes must adhere to environmental standards, such as using eco-friendly coatings and techniques. Optimizing workflows—e.g., adopting automated spraying equipment or efficient sanding tools—can enhance processing efficiency and increase production capacity.
