DFM Before Tooling
Engineering review considers customer drawings, material requirements, critical dimensions and manufacturability requirements before tooling.
Dongguan Manufacturing Base
Injection Molding Facility & Quality Control
Yiot Technology Co., Ltd. provides global sales and engineering support for international projects. Manufacturing is carried out at the approximately 12,000 m² Dongguan base operated by Dongguan Aoyuan Plastic Products Co., Ltd.
The manufacturing base combines automated injection molding, in-house mold manufacturing, DFM engineering and dimensional inspection for overseas OEM/ODM projects.

Automated Injection Molding Equipment
The Dongguan manufacturing base operates 49 automated injection molding machines from 90T to 1,200T. All 49 machines are equipped with robots. Machine selection depends on part size, material, part weight and mold structure.

Precision Mold Machining & Inspection Equipment
The in-house mold operation includes 31 mold-machining and dimensional-inspection units. The equipment data below is retained as confirmed by YIOT. Accuracy values describe the listed machine or inspection system and are not universal tolerances for injection-molded parts.
| Equipment Type | Equipment Accuracy | Working Stroke | Quantity | Origin |
|---|---|---|---|---|
| CNC Machining Center | — | 1000 × 800 × 600 mm | 12 | Japan |
| Coordinate Measuring Machine (CMM) | ±0.0005 mm | 900 × 800 × 700 mm | 3 | Germany |
| Vision Measuring System | ±0.001 mm | 300 × 250 × 200 mm | 3 | Taiwan, China |
| Wire Cut EDM | ±0.002 mm | 400 × 300 × 250 mm | 6 | Japan |
| Mirror EDM | ±0.002 mm | 400 × 350 × 300 mm | 7 | Switzerland |
Equipment accuracy is not the same as finished molded-part tolerance. Achievable part tolerances must be evaluated for each project according to part geometry, material, wall thickness, mold construction and production conditions.
Quality Management & Engineering Review
The Dongguan manufacturing base operates under an ISO 9001:2015 quality management system. Quality and validation requirements are reviewed against customer drawings, material requirements, critical dimensions and project-specific production needs.
Dimensional Inspection
Inspection requirements are defined according to drawings, critical dimensions and the agreed project validation plan.
In-house Mold Manufacturing
CNC machining, EDM, milling, mold fitting and mold assembly are supported within the Dongguan manufacturing operation.
Delivery Performance
YIOT reports a company-confirmed on-time delivery rate of 98%+. Project schedules remain subject to scope, validation requirements and agreed milestones.
Prepare Your Project for Engineering Review
Send your 2D/3D drawings, resin requirements, expected production volume and critical dimensions. The engineering team will review manufacturability requirements before tooling and quotation.
