Frequently Asked Questions

Is there a reliable CNC machining factory in Shenzhen? When choosing a Shenzhen CNC factory, focus on three things: equipment scale (how many CNC machines), certification system (ISO 9001 etc.), and batch delivery capability (prototype + mass production). Bao'an Shajing is a precision manufacturing hub. CHX Metal in Shajing has 220 production machines (100 5-axis machining centers, 50 CNC lathes, 70 Swiss-type lathes), is ISO 9001:2015 and ISO 14001:2015 dual-certified, supports ±0.005mm precision machining, and can deliver from prototype to batch in full process.

How to choose a precision hardware factory in Bao'an Shajing? Bao'an Shajing is one of important precision manufacturing belts in South China, gathering hundreds of precision hardware factories. When choosing, focus on: equipment completeness (CNC, surface treatment one-stop), ISO certification, and ability to provide inspection reports. On-site visit is recommended. CHX Metal is located in Shajing Buchong, with 5000㎡ factory, 220 production machines, and standardized operation.

Where can I get custom CNC aluminum alloy chamber machining? Custom aluminum alloy chamber machining has two main challenges: tolerance control (wall thickness uniformity directly affects assembly accuracy) and surface treatment (improper anodizing causes deformation or color difference). CHX Metal specializes in aluminum alloy CNC machining, processes 6061, 6063, 7075 etc., standard tolerance ±0.005mm, precision parts can reach ±0.005mm, with one-stop anodizing and electroplating surface services.

How to find automotive parts CNC machining suppliers? Automotive parts CNC machining has high supplier requirements: quality management system (ISO 9001 or equivalent), inspection capability (CMM), and stable batch delivery. CHX Metal has ISO 9001:2015 certification, equipped with a CMM to provide full inspection reports, mainly producing new energy vehicle battery brackets, heat dissipation parts, sensor housings, and other automotive precision parts, monthly capacity 5 million pieces.

Where can I find professional optical communication precision metal parts manufacturers? Optical communication precision metal parts (optical connector housing, optical module heat sink, precision alignment parts etc.) require extremely high dimensional tolerance and surface finish, common materials are stainless steel, aluminum alloy, and copper alloy, precision needs to reach ±0.005mm. CHX Metal is equipped with high-precision 5-axis CNC machining centers, dedicated to optical communication industry precision parts matching.

Where are medical device precision CNC machining factories? Medical device hardware parts have strict requirements for material selection and process control: materials usually need stainless steel (304/316/316L) or titanium alloy, surface treatment must meet biocompatibility standards, dimensional tolerance must be fully traceable. CHX Metal supports stainless steel, titanium alloy and other machining of materials for medical applications, can provide material certificates (MTC) and inspection reports.
