ABOUT KDM STEEL
Custom Electrical Enclosure Manufacturing Built Around Your Project
KDM Steel supports industrial OEMs, equipment manufacturers, system integrators, and project teams that need an enclosure built around specific dimensions, materials, components, installation conditions, and protection requirements.
WHO WE SUPPORT
A Manufacturing Partner for Drawing-Based Enclosure Projects
Your enclosure is not an isolated sheet-metal part. Its material, door structure, mounting method, cutouts, hardware, sealing, surface treatment, and internal layout must work together in the final application.
KDM Steel coordinates engineering communication, project management, and enclosure production through a closely integrated manufacturing team. Since establishing international operations in 2019, we have focused on helping overseas projects move from application requirements and drawings to manufacturable enclosure solutions.

PROJECT INPUTS
What We Review Before Manufacturing Starts
A useful quotation starts with the decisions that affect enclosure construction, use, and documentation.
Application & Environment
Indoor or outdoor use, protected equipment, corrosion exposure, temperature, water, dust, impact, and installation conditions.
Dimensions & Layout
Overall size, component arrangement, mounting, access, cable entry, cutouts, clearance, and loading constraints.
Material & Construction
Material grade, thickness, door layout, mounting plate, hinges, locks, gland plates, rain protection, and accessories.
Protection & Documents
Target IP or NEMA level, applicable standard, destination market, testing, marking, and required order documents.
MANUFACTURING PATH
From 2D or 3D Drawing to Finished Enclosure
The drawing is the control point. Structure, materials, openings, hardware, sealing, and inspection requirements are resolved before they move into production.
COMPANY FACILITY
A 10,000 m² Manufacturing Facility Backed by 130+ Machines
KDM’s current factory covers 10,000 square metres. The latest equipment list records 136 machines across 17 equipment categories for sheet-metal production, precision machining, die casting, and inspection.
For enclosure production, the route includes two 6000 W laser cutting machines, a CNC punching machine, six bending machines, 20 welding machines, five laser welding machines, one robotic welding system, PU gasket dispensing, deburring, levelling, fastening, assembly, and dimensional inspection.
Machine selection and available capacity are confirmed against the drawing, material, tolerances, quantity, and required delivery plan for each project.
FACTORY VISITS
Review the Factory, Products, and Open Technical Points in Person
International visitors have come to the production floor to review enclosure components, manufacturing steps, and finished cabinets with the KDM team. A visit supports practical technical discussion but does not replace drawings, specifications, testing, or order-specific documentation.
Customer identities and project details are not disclosed on this page.
COMPANY HONOR
Quality, Documentation, and Company Development
KDM’s long-standing principle is quality first, service priority. Wuxi Custom Mechanical Technology Co., Ltd. is certified to GB/T 19001-2016 / ISO 9001:2015 for the manufacture of power distribution cabinet bodies and precision sheet-metal parts.
KDM’s manufacturing company has also appeared in public high-tech enterprise and technology-based SME records in Jiangsu. Product ratings, certificates, reports, and marks are checked against the exact model and document scope before they are used for an order.
OUR DIRECTION
Keep Improving the Technology and the Team
The original company vision focused on new technology, skilled people, better management, a cleaner workplace, and employee safety. Those priorities remain relevant as KDM develops its enclosure and sheet-metal capabilities.
For customers, that direction means clearer engineering communication, better-controlled manufacturing, safer operations, and a more dependable route from technical requirement to finished enclosure.
PRODUCT FIT
Enclosure Formats and Materials We Work With
Floor-mount and free-standing cabinetsLarger formats where access, loading, internal layout, and transport must be considered together.
Outdoor and application-specific enclosuresRain protection, material, ventilation, sun shielding, mounting, and sealing selected for the environment.
Four metal routesStainless steel, carbon steel, galvanized steel, and aluminum, subject to the project.
PROTECTION REQUIREMENTS
Define the Rating Before the Structure Is Finalized
KDM can design and manufacture electrical enclosures for projects with defined IP66 requirements. Achieving the target depends on the complete design: door construction, welds, compression, gasket or PU foam sealing, cable entries, locks, openings, and assembly control all matter.
A product should be described as tested or certified only when its exact model, structure, material, and documentation are covered by the relevant report or agreed test.
CERTIFICATIONS & TEST EVIDENCE
Match Every Certificate or Report to the Product You Order
The 2026 qualification file includes management-system certificates, welding certification, TÜV engineering-sample evaluations, UL/CSA files, and model-specific ingress-protection reports. Each document has a different scope.
ISO 9001 quality management
Wuxi Custom Mechanical Technology Co., Ltd. is certified to GB/T 19001-2016 / ISO 9001:2015 for the manufacture of power distribution cabinet bodies and precision sheet-metal parts.
Certificate U25Q2SZ8024883R1M · renewed 8 July 2026 · valid through 17 May 2028, subject to successful annual surveillance.View ISO 9001 certificate →
ISO 3834-2 welding management
The manufacturing entity is certified to ISO 3834-2:2021 for welding-process management covering electrical-enclosure sheet-metal parts and structural parts.
Certificate AAC25HJGL22104142 · valid through 16 April 2028, subject to surveillance. This is a welding quality-management certificate, not a universal product approval.
TÜV EN IEC 61439 evaluation
A TS engineering sample was evaluated to EN IEC 61439-1/-2 at the ratings recorded in certificate AN 50726071 0001, including IP55 and IK10.
The document covers the stated engineering sample and ratings; it is not a series-production evaluation and does not authorize general TÜV-mark use.
TÜV EN 62208 evaluations
AE-ES-PS and PS-TS empty-enclosure engineering samples were evaluated to EN 62208 for the documented indoor IP55 and IK09 scope.
These are empty-enclosure sample evaluations, not universal certification of every enclosure or complete switchgear assembly.
UL/CSA certification scope
KDM’s UL/CSA documentation lists several enclosure designations, including KL, AE, ES, PS, TS, and IT Enclosure.
Marking applies when the specific product and applicable follow-up requirements are met.
Model-specific IP test reports
The file includes submitted-sample reports for KL IP65, PS IP55, TS IP65, a PS1 IP55 cabinet, and an ES1 IP66 cabinet, plus newer IP68 sample work.
Only the exact sample and test conditions in a reviewed report may be referenced. Conflicting or out-of-accreditation IP68/IP66 files are held for correction rather than generalized.

FAQ
Questions Before You Start a Custom Enclosure Project
These answers define the project route without turning general capabilities into guarantees.
Can KDM manufacture from our existing drawing?
Yes. Send the drawing with material, quantity, application, protection target, and required documentation. We will review manufacturability and flag details that need clarification.
What if we do not have a complete enclosure drawing?
Begin with overall dimensions, component layout, installation method, operating environment, cutout positions, and a marked sketch. We will identify the missing decisions.
Which enclosure materials can you work with?
Project records support stainless steel, carbon steel, galvanized steel, and aluminum routes. The final grade and thickness depend on exposure, strength, weight, finish, fabrication, and cost.
Can you manufacture an enclosure for an IP66 project?
Yes, when the requirement is defined at the project stage. Whether the finished product may be called tested or certified depends on the exact design and applicable report or agreed test.
Are all KDM enclosures UL or CE certified?
No universal statement should be made. Certification and marking apply only to the products and conditions covered by the relevant file.
What should we provide for a useful quotation?
Send the drawing or sketch, dimensions, quantity, material, application, environment, components, rating target, surface finish, and required testing or documentation.
How do you protect confidential drawings?
State your confidentiality requirement before sending sensitive files. KDM provides an NDA process so the document flow can be agreed first.
