Custom CNC Components That Fit the First Time—and Stay Consistent Across the Batch.
When one mounting face, bore or shaft is wrong, your entire assembly can stop. Yishang manufactures drawing-based metal components for B2B production programs, supporting sample approval before repeat batch orders.

Choose Yishang When the Machined Component Must Work Inside a Larger Product.
You are not buying machine time. You need a metal component that arrives ready to locate, mount, seal, rotate or connect correctly inside your equipment.
Complete CNC Components
Custom plates, blocks, housings, flanges, shafts, spacers, bushings and mounting elements manufactured from your drawing.
You receive finished metal components ready for your next assembly step.
Machined Interfaces on Fabricated Structures
Critical mounting faces, bearing seats, bores and threads completed after welding, bending or forming when the final structure controls alignment.
Your interface is machined in the condition in which it will actually be assembled.
CNC + Sheet Metal Subassemblies
Machined blocks, rails, shafts, inserts and plates coordinated with Yishang-made frames, cabinets, guards and enclosure structures.
You reduce supplier handoffs and avoid disputes over which component caused the mismatch.
The Expensive Problems Usually Appear After a Cheap Quote.
A low unit price means little if the batch later needs sorting, rework or replacement. We review the risks that affect your delivered cost before production begins.
The Quote Changes Later
Important material, finish, quantity or inspection details are missing from the RFQ.
We identify the open questions before quoting so your comparison is based on the real scope.
Components Pass but Do Not Fit
Individual dimensions may look acceptable while the mounting faces, bores or hole patterns do not align in your assembly.
We confirm which features work together and inspect the relationships that matter to installation.
The Sample Passes but the Batch Drifts
A good first article does not guarantee that later production will stay consistent.
The approved sample is tied to a repeatable route, in-process checks and final lot release.
Finishing Changes Fit or Appearance
Coating, anodizing, polishing or handling can affect threads, bores, mating faces and visible surfaces.
We define protected and cosmetic areas before finishing, not after the appearance problem is found.
Damage Appears at Your Factory
A correct component can still arrive scratched, mixed or difficult to identify on the production line.
Component separation, surface protection, batch identification and export packing are included in the release plan.
We Confirm What Must Fit, What Must Stay Visible and What Cannot Change.
Your drawing gives the dimensions. Your product tells us which dimensions can stop assembly, create leakage, affect motion or cause a visible quality complaint.
If a requirement is unclear, we ask before production instead of making a convenient assumption that becomes your assembly problem.
Where the Component Locates
We identify the faces and points your assembly uses to position the component, so inspection reflects real installation.
Which Features Must Match
We confirm mating hardware, hole patterns, thread depth, bearing or shaft fits and other interfaces connected to surrounding components.
What Can Distort During Production
Thin walls, deep pockets, welding and finishing are reviewed early where they could change alignment or create unstable results.
Which Surfaces Customers Will See
Visible, sealing, sliding and mounting faces receive different appearance, protection and acceptance requirements.
We Choose the Manufacturing Route Around Your Component—not Around a Machine List.
Your drawing, material, order volume and assembly requirements determine the process. The goal is a stable delivered component, not unnecessary machining complexity.
CNC-Machined Plates, Blocks and Housings
Equipment plates, mounting blocks, housings, pockets, interfaces and multi-face components made from your drawing.
A finished component with the mounting relationships, deburring and surface requirements confirmed for assembly.
Custom Shafts and Round Components
Shafts, pins, spacers, bushings, sleeves and threaded round components used in equipment and structural assemblies.
The required fit, shoulder position, thread condition and protected surface arrive ready for the next operation.
CNC Combined With Fabrication
Frames, brackets, enclosures and structures that need machined interfaces after welding, bending or forming.
One supplier coordinates the fabricated structure and the final machined interfaces that determine assembly fit.
The Sample You Approve Becomes the Reference for the Batch.
Approval is not the end of quality control. We connect your approved sample to the production method, checks, finishing and packing used for repeat orders.
Confirm the RFQ
We review the current drawing, material, quantities, mating features, finish, documents and unresolved requirements.
Approve the First Article
The sample confirms fit, appearance and the agreed critical features before repeat production moves forward.
Lock the Production Method
The approved manufacturing route and checkpoints are carried into repeat production instead of being reinvented for each batch.
Check the Batch
Agreed features are verified during production so variation is found before the complete lot reaches final inspection.
Protect and Release
Quantity, appearance, records, identification and protective export packing are confirmed before shipment.
Need Machined Interfaces Inside a Frame or Enclosure? Keep Them Under One Supplier.
If the CNC supplier and fabrication supplier work from different assumptions, you may receive two acceptable components that do not assemble. Yishang can coordinate both scopes around the complete product.
One Shared Assembly Reference
Machined and fabricated elements are reviewed against the same mounting and locating points.
Critical Features Completed After Welding
Where your drawing requires it, key faces or bores are finished in the final welded condition.
Hardware and Service Access Reviewed Together
Threads, inserts and fasteners are checked together with panels, guards, doors and maintenance openings.
Fit Checked Before Shipment
When included in the order scope, mating elements are checked together before protection and export packing.
Choose the Metal That Fits the Product and the Production Plan.
Yishang supplies finished custom components, not raw material. We confirm the grade, condition, finish and documentation required for your application.
Aluminum
Lower weight, corrosion resistance, efficient machining and optional anodized appearance.
Alloy, condition, visible faces, anodizing expectations and protected interfaces.
Stainless Steel 304/316
Corrosion resistance, clean appearance and suitability for demanding service environments.
Grade, surface requirement, passivation or polishing needs, thread behavior and critical finish areas.
Mild / Carbon Steel
Strength, cost control and compatibility with many industrial structures and coated assemblies.
Grade, heat-treatment needs if any, corrosion-protection route and coating-free functional faces.
Brass
Machinability, appearance, wear behavior and selected electrical or fluid-handling applications.
Grade, visible surfaces, thread or sealing features and tarnish-protection expectations.
Red Copper
Electrical and thermal conductivity for selected drawing-based functional components.
Grade, conductivity requirement if applicable, handling marks, joining method and finish protection.
Know What Was Checked Before the Batch Leaves China.
Inspection should give your team useful confidence, not a stack of irrelevant paperwork. We agree which features, appearance requirements and documents matter to your order.
Critical Feature Checks
Agreed dimensions and interfaces are checked during setup and production so variation is found before the lot is complete.
Fit and Appearance Review
Mating relationships, deburring, visible surfaces, finish protection and handling condition are reviewed before release.
Order Documents
Inspection results, material documents and other agreed records are supplied when they are included in your RFQ and purchase order.

Questions Your Team May Have Before Requesting a Quote.
Can you make a sample before volume production?
Yes. A sample order can be the first step in a B2B production program, allowing fit, appearance and critical features to be approved before repeat orders.
What machining tolerance can you hold?
The appropriate tolerance depends on material, feature size, geometry, process and function. We review the drawing and confirm realistic expectations for the features that matter rather than applying one tolerance claim to every component.
Can CNC machining be combined with sheet metal fabrication and welding?
Yes. When defined in the RFQ, the scope can combine machined interfaces with Yishang-made frames, cabinets, panels, guards, welding, finishing, assembly, inspection and packing.
