Multi-cavity Mold refers to a mold system in which multiple cavity is set in the same mold frame and multiple molding or different components are produced simultaneously through a single injection molding cycle. This technology is widely used in industries such as automobiles, home appliances, communications, medical care, and consumer electronics, and is suitable for a variety of engineering plastics and composite materials.
Technical Features
• Multi-cavity design: A single set of molds can be configured with 2 cavity, 4 cavity, 8 cavity or even more cavity, and can be flexibly adjusted according to capacity requirements.
• Complex molding: supports special shape, thin wall, high stiffness and multi-material co-injection (2K/3K) and other processes.
• Hot runner system: equipped with a balanced hot runner or gateless system to ensure uniform distribution of melts in each cavity.
• Automated matching: linking with multi-station injection molding machines, robots or mold releasers to achieve high-efficiency unmanned production.
Core advantages
• Improve production capacity: Multi-chamber parallel injection molding can produce multiple products per cycle, and the efficiency can be improved several times.
• Reduce costs: higher raw material utilization rate, save scraps; mold depreciation and energy consumption per unit product are diluted.
• Ensure consistency: the same mold is formed in the same batch, and the parts size and performance are more stable.
• Quick response: Suitable for rapid production and delivery of medium and high batch products.
Quality control
• Strict mold test: Verify the mold temperature, pressure holding and demolding parameters through Moldflow simulation and first-piece measurement.
• Precision machining: The cavity and core are made of high-grade mold steel (such as 1.2344, H13) to ensure wear resistance and corrosion resistance.
• Online monitoring: The injection molding machine is equipped with melt pressure, temperature and floating flange sensors to monitor product quality in real time.
• Back-end inspection: dimensional tolerance, appearance defects and physical performance test, tracking and recording data throughout the process.
Application Cases
• Automobile electrical connector housing: 4-cavity hot runner mold, daily output of 200,000 pieces.
• Household appliance panel: 8-cavity two-color (2K) mold, hardware support and soft touch buttons completed in one injection molding.
• Industrial instrument housing: 6-cavity gateless mold, and the finished product does not require secondary trimming.
in conclusion
Multi-cavity Mold injection molding technology has become the first choice for mass production of modern plastic parts due to its high production capacity, high consistency and low cost. Enterprises can flexibly design cavity numbers and runner layouts according to product development rhythm and market demand to achieve efficient, stable and sustainable manufacturing solutions.
