Product Overview
Our Dental Impression Tray Plastic Injection Mould specializes in manufacturing high-quality plastic injection molds and finished parts for dental disposable impression trays, serving the dental medical consumables supporting industry. We provide a one-stop injection molding solution integrating precise contour design, medical-grade cleanliness, and stable strength, addressing the core needs of oral consumables manufacturers. Unlike ordinary Appliance Plastic Housing Manufacturing and White Goods Components Plastic mould, this mould is engineered specifically for dental medical scenarios, with multi-cavity design to support high-speed mass production. It ensures the produced impression trays fit perfectly with dental arches, maintain strict hygiene standards, and balance rigidity and toughness, enabling precise, clear mold taking for dental restoration and orthodontics, while helping customers achieve cost reduction and efficiency improvement.
Technical Specifications
Our mould boasts detailed and reliable technical parameters to meet global purchasers’ evaluation needs. It supports customizable arch sizes from children to adults, covering upper and lower jaw models, with tray lengths ranging from 50mm to 120mm, suitable for edentulous jaw, partial dentition, and full dentition impression needs. Conventional materials are medical-grade high-toughness PP, and we also offer high-temperature sterilization modified materials for reusable impression trays. The main body wall thickness is controlled within 1.0mm-1.5mm, with edge thickness adjusted to 1.2mm-1.8mm to balance rigidity, toughness, and raw material cost. Dimensional accuracy is strictly controlled: multi-cavity profile tolerance ≤±0.1mm, grid structure position tolerance ≤±0.05mm. Made of S136 corrosion-resistant steel, the mold has a service life of over 1 million cycles. Cavity design is customizable (1-out-8/1-out-16/1-out-32) to balance production efficiency and cost, and it is compatible with 150T-300T high-speed injection molding machines for 16-32 cavity molds.
Product Features
Compared with competitors, our mould has unique advantages supported by advanced technology and strict quality control. Firstly, precise contour and perfect fit: the tray’s contour tolerance is strictly controlled within ±0.1mm, with edges adapted to oral shapes for different tooth positions, ensuring even filling of impression material without curling or leakage, and the integrated high-precision mesh structure prevents material detachment to maintain mold integrity. Secondly, medical-grade cleanliness and safety: the mold cavity has no hygiene dead corners, easy to clean and disinfect, compatible with medical-grade PP, and finished trays meet dental medical device biological evaluation standards with no harmful residues or oral irritation. Thirdly, high-speed mass production compatibility: excellent multi-cavity flow channel balance ensures consistent filling pressure and stable shrinkage, minimizing size deviation, compatible with automated packaging lines, and high yield rate reduces unit costs. Finally, balanced rigidity and toughness: reasonable material matching prevents deformation during use, and the thin-walled design saves materials and costs, suitable for disposable use.
Application Scenarios
As the key highlight of this product, our mould has a wide range of application scenarios, fully meeting the diverse needs of dental consumables manufacturers and helping purchasers expand market coverage. It is widely used in manufacturing dental clinic disposable impression trays for daily diagnosis and treatment, special impression trays for orthodontic modeling to record precise tooth shapes, mold trays for dental restoration denture production to support customized dentures, and complete denture edentulous jaw impression trays adapting to edentulous patients’ needs. It also supports the production of reusable disinfection dental impression trays (compatible with high-temperature sterilization materials) and customized development of other oral diagnostic plastic consumables, such as dental mixing cups and special dental trays. These scenarios fully demonstrate the mould’s versatility and practical value in the dental medical industry.
Certifications and Compliance
We attach great importance to product compliance to enhance purchaser confidence. Our Dental Impression Tray Plastic Injection Mould and finished products fully comply with the ISO13485 Medical Device Quality Management System, ensuring every production link meets strict medical requirements. Raw materials pass professional medical-grade compliance testing, and finished trays meet dental medical device biological evaluation standards, with no harmful residues or oral irritation. We have established a special quality control system for dental medical device molds, including 3D full-size cavity testing, first piece verification, and batch consistency testing, ensuring the non-conformance rate is controlled within 0.01%, fully meeting global dental market access requirements.
Customization Options
We offer flexible customization solutions to meet your specific needs. Size customization: tailored arch sizes from children to adults, covering upper and lower jaw models, and tray lengths ranging from 50mm to 120mm for edentulous, partial, and full dentition needs. Material customization: conventional medical-grade high-toughness PP; optional high-temperature sterilization modified materials for reusable impression trays. Cavity customization: 1-out-8/1-out-16/1-out-32 cavity designs, customized according to your production capacity to balance efficiency and cost. Structure customization: optimize mesh structure, edge edging, and demolding design, combined with DFM analysis to improve product manufacturability and reduce production costs.
Production Process
Our strict production process and quality control system ensure mold precision and stability. The process starts with the design stage: targeted impression tray design, CAE mold flow analysis to optimize flow channel and cooling water path, and integrated mesh and edge design to eliminate post-processing. Next is the machining stage: imported high-precision CNC machining for cavity, tray contour, and grid structure; slow wire cutting and precision grinding for the parting surface (clamping gap ≤0.003mm); fine polishing for the cavity surface to ensure smooth demolding. Then comes material and treatment: using S136 corrosion-resistant mold steel, undergoing vacuum quenching, secondary stress relief annealing, and nitride hardening to enhance mold service life and performance. Finally, quality control: raw material medical-grade testing, 3D full-size cavity testing, first piece verification, and batch consistency testing; we also provide 5-10 day rapid sample verification, lifelong mold maintenance, and medical device registration technical support.
