Custom Precision Sheet Metal Prototypes and CNC Punching Services

1. Product Overview

Shenzhen Hongsinn Precision Co., Ltd. specializes in the manufacturing of custom precision components, providing global clients with services including sheet metal prototyping, light sheet metal fabrication, and CNC sheet metal punching.

Based on client-provided CAD drawings, 3D models, product samples, and technical specifications, we evaluate materials, sheet thicknesses, hole layouts, bending structures, and surface finishing options. We offer tailored manufacturing support for product R&D, prototype validation, small-batch pilot runs, and mass production.

Utilizing processes such as laser cutting, CNC punching, bending, deburring, welding, and appropriate surface treatments, we fabricate metal sheet parts in diverse shapes and structures. Our products meet application requirements for electronic device enclosures, industrial mounting brackets, instrument panels, ventilation panels, and light metal structural components.

Hongsinn Precision prioritizes adherence to drawing specifications, critical dimensions, and assembly precision. We assist clients in optimizing part designs and enhancing production efficiency, while also providing manufacturing support for overseas OEM/ODM projects.

Core Product Advantages

Custom Sheet Metal Prototypes
Customization of product profiles, mounting hole locations, and structural dimensions based on drawings and 3D models; suitable for new product development, design validation, and prototype fabrication.

CNC Sheet Metal Punching

Processing of various hole shapes—such as round, square, and slotted holes—based on part geometry and equipment capabilities; suitable for equipment panels, mounting brackets, and components with standard hole patterns.

Light-Gauge Sheet Metal Processing

Targeted at lightweight brackets, thin-gauge enclosures, and structural components; utilizes a combination of cutting, punching, and bending processes to meet structural and assembly requirements.

Dimensional Inspection & Custom Production

Verification of critical dimensions, hole locations, bend angles, and surface finish against product drawings and quality specifications; supports assessment for prototypes, small-batch runs, and mass production orders.

Product Applications

Electronic Device and Instrument Enclosures

Used for controller housings, instrument panels, internal mounting plates, and protective metal structures for electronic equipment; mounting holes and connection points can be machined according to design specifications.

Industrial Automation Equipment

Suitable for sensor brackets, mounting baseplates, connecting plates, equipment fasteners, and lightweight metal structural components, meeting requirements for equipment installation and component positioning.

Ventilation and Heat Dissipation Structures

Used for ventilation panels, heat dissipation shrouds, equipment guards, and perforated metal components; hole shapes and layouts can be configured according to design requirements.

Automotive and Mechanical Auxiliary Parts

Suitable for mounting brackets, connecting tabs, auxiliary installation components, and non-safety-critical metal structural parts; specific applications must comply with relevant drawings and industry standards.
