Product Summary
Our CPAP Machine Housing Plastic Injection Mould is a professional Precision Mold Design and Build solution dedicated to medical and home respiratory equipment manufacturers. As a core Custom Plastic Injection Tooling, it integrates large-size compatibility, low warpage, medical-grade safety, and reliable sealing, perfectly meeting the strict requirements of CPAP machines for module assembly accuracy, long-term stable operation, and medical disinfection. Complementing our diverse product portfolio—including Household Appliance Mould , Medical Patient Monitor Housing Plastic Mould, Infrared Thermometer Housing Plastic Injection Mould, Blood Glucose Meter Housing Plastic Mould, and Water Purifier Plastic Filter Housing Mould—it provides comprehensive one-stop molding services to support purchasers’ mass production needs.
Key Highlight: Production Process (Precision & Quality Assured)
Our streamlined yet rigorous production process is designed to deliver consistent, high-quality molds, addressing the top concern of global purchasers—reliable mass production. The process starts with targeted CPAP housing design: we use CAE mold flow analysis to optimize multi-point pouring positions and zoned cooling water circuit layouts, ensuring uniform filling of thin-walled cavities, dispersing internal stresses, and fundamentally reducing large-size panel warpage and deformation.
Next, large five-axis CNC machining centers perform precision cavity machining, ensuring accurate reproduction of complex curved contours that align with ergonomic CPAP designs. The surface texture is achieved via professional chemical etching, with a 95%+ design reproduction rate for uniform matte anti-slip texture. The parting surface undergoes large slow-wire multi-cutting and manual precision grinding, with mold clamping gaps controlled within 0.005mm and flash thickness within 0.01mm, minimizing post-processing costs.
Mold material treatment is equally strict: high-purity pre-hardened P20HH mold steel (upgradable to S136 corrosion-resistant steel) undergoes two stress relief annealing treatments to eliminate internal stresses, while cavity nitriding enhances surface hardness and anti-sticking performance—ensuring long-term dimensional stability and extended mold service life.
Core Advantages & Purchaser Value
Our mould controls large-size warpage within 0.25mm/m, with functional module tolerance ≤±0.1mm and interface positioning tolerance ≤±0.03mm, ensuring a nearly 100% automated assembly pass rate and reducing labor costs. Medical-grade low-VOC plastics meet UL V-0 flame-retardant standards, with stable insulation and no odor, safeguarding healthy respiratory environments. The humidification tank chamber features precise sealing lines to prevent water/air leakage, guaranteeing stable ventilation pressure. Integrated structures (screen frame, module positions, battery compartment) eliminate post-processing, cutting assembly costs further.
Application Scenarios & Versatility
This mould is widely applicable to home sleep snoring non-invasive CPAP machine host shells, hospital ward invasive/non-invasive ventilator casings, portable emergency transport ventilator protective shells, ventilator humidification tank chambers, and household oxygen concentrator plastic components. It also supports customized development for other respiratory equipment like nebulizers and oxygen concentration monitors, complementing our Custom Kitchen Appliance Plastic Mould and Air fryer accessory plastic Mould to serve diverse industrial needs.
Compliance, Customization & Support
The mould complies with ISO13485 and UL standards, with a full-process quality control system keeping non-conformance rate within 0.02%. We offer flexible customization: size (200mm×150mm to 500mm×400mm), materials (medical-grade PC/ABS, flame-retardant PC, customized disinfection-resistant options), cavity designs (1-out-1 for large hosts, 1-out-1/1-out-2 for portable models), and compatibility with 250T-1000T injection molding machines. We deliver 2-3 molds monthly, with 15,000 finished products capacity; new customized molds take 30-40 days (urgent available), bulk orders 7-15 days, with lifelong maintenance and medical device registration support.
