Frequently Asked Questions
What is precision injection molding?
Precision injection molding produces plastic parts with controlled dimensions, repeatability, and consistent process requirements. Achievable tolerances depend on part geometry, material, wall thickness, mold design, and production conditions. Yiot Technology Co., Ltd. provides global sales and engineering support, while the Dongguan manufacturing base provides in-house mold manufacturing, DFM engineering, injection molding, and dimensional inspection using 49 automated machines from 90T to 1,200T.
What is the typical tolerance for precision injection molding?
Injection molding tolerances must be evaluated for each project because they depend on part size, geometry, resin, wall thickness, mold construction, and production conditions. The engineering team reviews critical dimensions during DFM and verifies finished parts using dimensional inspection equipment. CNC mold-component machining accuracy can reach up to ±0.003 mm for applicable features and project requirements; this is not a universal tolerance for injection-molded parts.
How long does custom injection mold manufacturing take?
Typical custom mold lead time is 15–30 days, subject to mold complexity, cavity count, material, finish, validation, and project requirements. The in-house mold manufacturing operation supports 50+ new custom molds per month, depending on mold complexity, structure, project mix, and scheduling. YIOT has a company-confirmed 98%+ on-time delivery rate and provides DFM engineering support before tooling.
What materials can YIOT injection mold?
YIOT Technology processes a comprehensive range of engineering thermoplastics: ABS, PC, PP, PA (Nylon 6 and Nylon 66), POM (Acetal), PBT, PPS, PEEK, TPU, TPE, PMMA (Acrylic), and glass-fiber reinforced compounds. Material selection is guided by the part's mechanical requirements (tensile strength, impact resistance), thermal environment (continuous use temperature), and chemical exposure. Our engineering team provides expert material recommendations during the DFM phase to balance performance and cost.
What industries does YIOT Technology serve?
YIOT supports projects in four verified sectors: Automotive, Medical, Electronics, and Industrial Equipment. Yiot Technology Co., Ltd. provides international sales and engineering support, while the Dongguan manufacturing base provides custom mold manufacturing, injection molding, DFM engineering, dimensional inspection, and OEM/ODM production support. The Dongguan manufacturing base operates under an ISO 9001:2015 quality management system.
How to choose a reliable injection molding manufacturer in China?
Buyers should review factory scale, in-house tooling, injection molding capacity, quality management, DFM support, inspection equipment, project communication, and verifiable factory access. YIOT's Dongguan manufacturing base has approximately 12,000 m², 49 automated injection molding machines from 90T to 1,200T, in-house mold manufacturing, and an ISO 9001:2015 quality management system. Customers and authorized third parties may arrange factory audits and project evaluations.
