PLC & Industrial PC Enclosures
Sheet metal housings precisely machined for PLCs, IPCs, and I/O modules — complete with cable entries, knockout zones, and mounting patterns tailored to your design.
High-Reliability Precision Components for EMC-Critical Automation Systems
We engineer robust custom enclosures, structural components, and precision panels for next-generation automation systems — from ASRS and robotics to IoT terminals. Our solutions support intelligent operation while minimizing hardware-related downtime.
Why Precision Engineering Matters in Industrial Automation
In modern industrial environments, automation systems face relentless mechanical and electrical stress — from vibration and EMI to thermal buildup. When components like PLC enclosures or control modules fail due to heat or poor shielding, costly downtime follows.
Built for Reliability: Precision CNC, Tolerances, and EMC Shielding
At Cherying, we solve these problems through precision CNC machining, EMI-conscious design, and exacting quality standards. Every bracket, panel, and enclosure is built to ±0.01mm tolerances and optimized for strength, thermal dissipation, and EMC protection.
Precision Components for Industrial Control & Automation Systems
We design and manufacture high-performance enclosures, brackets, and thermal elements to keep your PLCs, drives, and control modules protected, organized, and efficient — from small DIN‑rail parts to complete panel assemblies.
Door Panels & HMI Interfaces
Front panels with precision cut‑outs for HMIs, pushbuttons, and key switches — allowing clean layouts, intuitive labels, and fast control cabinet integration.
Mounting Plates & DIN‑Rail Brackets
CNC‑cut structural plates that hold terminals, relays, and power supplies securely in place — simplifying panel wiring and reducing maintenance overhead.
Thermal & EMC Protection Hardware
Custom-designed heatsinks, shield plates, and covers that ensure thermal regulation and EMI protection for drives, motion controllers, and power modules.
Precision CNC & Sheet Metal Capabilities for Automation Hardware
Whether for rapid prototyping or stable long-term production, Chenying delivers consistent and reliable enclosures and control components using advanced CNC machining and sheet metal fabrication — tailored for the rigorous demands of automation panels and control cabinets.

Certifications & Delivery Compliance
- Material certs for aluminum, steel, and stainless grades available on demand.
- Supports CE, UL, and RoHS compliance for industrial control assemblies.
- Protected handling and packaging to safeguard coated or anodized surfaces.
- Clear labels and part numbers for seamless BOM integration and inventory control.
- Built for repeat orders — consistent quality across production batches.
Case Study: Redesigning a Robotics Controller for Thermal & EMC Performance
Discover how we helped an advanced automation manufacturer solve critical heat and EMI issues in their robot controller — without changing the enclosure footprint.
The Challenge
The client's compact controller chassis was overheating during high-load cycles and repeatedly failing EMC immunity testing. They required a thermally optimized, EMI-stable solution that fit their existing form factor.
Engineering Solution
Our team selected AL6063 aluminum for superior heat dissipation. We refined the heat sink fin profile through DFM and airflow analysis, then machined the enclosure on a 5-axis CNC in a single setup to maintain gasket seal alignment for EMC shielding.
Final Result
The new design operated 12°C cooler at full load and passed all EMC tests on the first attempt. We also achieved a 15% reduction in unit cost thanks to optimized machining and consolidated processes.
