ABOUT PROLEANTECH / SHENZHEN, CHINA
A manufacturing team.
A factory you can visit.
ProleanTech is a precision manufacturing company supporting engineering and procurement teams from complex prototypes to production runs.
Our Shenzhen workshop brings machining, engineering review and inspection together. We review your geometry, material and critical features, then establish the production route and quality requirements for your part.

MANUFACTURING CAPABILITIES
Complex parts.
A clear route to making them.
CNC machining is our core. Sheet metal fabrication adds a route for brackets, panels and enclosures. Start with the part you need to make.
Sheet metal fabrication
Brackets, panels and enclosures through cutting, bending and joining.

Validate the design.
Build the batch. Plan for production.
As quantity grows, the manufacturing route needs to evolve with it. We review tooling, material, inspection and process choices for each stage.
- 01
Rapid prototyping
Check fit, function and design feasibility before committing to a production route.
Explore prototyping ↗ - 02
Low-volume production
Use pilot and bridge batches to refine the specification, setups and acceptance checks.
Discuss your batch ↗ - 03
Mass production
Review dedicated tooling and repeatable processes for the planned quantity and delivery schedule.

MATERIAL → SURFACE → FINAL REQUIREMENT
The right material.
The right finish. One specification.
First choose the base material for the job. Then define how the surface should perform. Review both against the dimensions that matter.
01 / CHOOSE THE BASE MATERIAL
What must the part withstand?
Start with load, temperature, weight, corrosion and contact conditions. Confirm the grade and condition for your application.
- Metals
- Aluminum, stainless steel, steel, copper alloys and titanium
- Engineering plastics
- POM, nylon, PEEK and other engineering plastics
02 / DEFINE THE SURFACE
What must the surface do?
Specify appearance, wear, corrosion protection and roughness. Allow for coating thickness, masking and mating surfaces.
- Protection & appearance
- Anodizing, plating and powder coating
- Texture & surface condition
- Bead blasting and specified roughness
WHEN HARDNESS MATTERS
Heat treatment changes material properties. Review the required condition and its effect on final dimensions separately from the surface finish.
Explore heat treatment ↗QUALITY & INSPECTION
Quality built into the process.
Evidence you can review.
Material verification, dimensional inspection and defined acceptance criteria connect your drawing to the parts delivered. Inspection methods and reports are agreed for your order.
Dimensions checked against the drawing.
Identify datums and functional features. Confirm the measurement method and the dimensions to include in your report.
Material identification with an alloy analyser.
Our inspection team uses a handheld analyser for alloy identification. Specify the grade, acceptance criteria and documentation your project requires.
ENGINEERING & DIGITAL PRODUCTION MANAGEMENT
Keep the specification
connected to the job.
Digital production management organizes job requirements and process progress. It supports production control, quality consistency and delivery planning as your project moves through the workshop.
Drawing revision, process route and inspection requirements need to stay aligned. Changes are reviewed before they become manufacturing instructions.

More manufacturing FAQs ↗What should I send for a quote?
Send a CAD model or dimensioned drawing, quantity, material, finish, critical tolerances and any inspection report requirements. Send what you have; an engineer can discuss missing details.
How are my drawings kept confidential?
Your drawings and project files are treated as confidential when you enquire. You can request a quote directly. An NDA is available as an additional option if an internal policy or project requirement calls for it. Read our privacy policy → · Optional NDA →
How are tolerances and lead time confirmed?
Geometry, material, process and finish determine feasibility. Project tolerances, price and lead time are confirmed through drawing review and the quote.
Can inspection reports accompany the parts?
Specify dimensional reports, material documentation and first article inspection when requesting your quote. Scope, cost and lead time are confirmed for your project.

DESIGN & MANUFACTURABILITY
Will this geometry machine cleanly?
Review tool access, internal radii, wall thickness and thread features before finalising the design.
Open design guidelines ↗TOLERANCES & INSPECTION
Which dimensions need tighter control?
Identify functional datums, mating fits, tolerance call-outs and the surfaces to inspect.
Review standards & tolerances ↗SURFACE REQUIREMENTS
What should the finish specification include?
Compare protection and appearance, and consider coating thickness, masking and final dimensions.
