Prismatic parts machined to your drawing
We favor sturdy textiles, solid hardware, refillable vessels, and finishes that can handle daily use without feeling disposable.
DRAWING REVIEW AVAILABLE
Custom CNC machined parts manufactured from your 2D drawings and 3D CAD files — one-off prototypes, engineering validation builds and low-volume production in metals and engineering plastics, with requirements reviewed before quotation.
Manufactured in Dongguan, Guangdong, China. Every project is reviewed against your drawing requirements before quotation.

Drawing-based manufacturing

BUILD-TO-PRINT MANUFACTURING
YSBK Parts is a custom CNC machining company working from customer-defined engineering data. We do not supply standard catalogue parts or modify stock components — every part is manufactured according to your approved drawing and CAD model. If the drawing and CAD model differ, we ask you to confirm
STEP, STP, DWG, DXF and PDF files accepted. The drawing controls dimensions, tolerances and critical features.
Complete material specification with grade and condition, from a single prototype to repeat small batches.
Critical tolerances, surface finish and inspection or documentation requirements, identified before quotation.
MACHINING CAPABILITIES
Core CNC machining processes and coordinated operations for custom parts manufactured from your drawings and CAD files.
We favor sturdy textiles, solid hardware, refillable vessels, and finishes that can handle daily use without feeling disposable.
Each collection starts with a familiar use case: the commute, the kitchen counter, the weekend bag, or the desk that never stays empty.
Clear shipping windows, straightforward returns, and practical care notes make the purchase feel easy before and after delivery.
ENGINEERING MATERIALS
Material availability is confirmed for every order during the RFQ stage. We do not substitute one grade or condition for another without your written approval.

PROTOTYPE TO PRODUCTION
YSBK supports one-off prototype parts and engineering validation builds manufactured directly from your approved drawings and CAD files. A single prototype can be used for assembly checks and engineering review before a low-volume batch is released, and design iterations between drawing revisions ar
Single parts for assembly checks, engineering review and early customer feedback, manufactured to the approved drawing revision.
Changes approved during validation are incorporated into an updated drawing and CAD files before repeat production.
When a prototype is approved for production, use the production-intent material, controlled drawing revision and agreed inspection scope.

SMALL BATCHES & REPEAT ORDERS
Low-volume CNC machined parts cover small production batches and repeat orders manufactured to a released, controlled drawing revision. Each order is reviewed against the current drawing and CAD revision, quantity, material, tolerances, secondary processes and inspection requirements — so repeat bat
Short production runs that bridge the gap between first article and full production.
Repeat orders reviewed against the approved first article, with material availability and inspection scope confirmed per order.
Drawing and CAD revisions are checked before every quotation; conflicting files are confirmed with you, not assumed.

BEFORE YOU QUOTE
Before quotation, each RFQ is reviewed so both sides work from the same understanding. The review typically covers file consistency between drawing and CAD model, material and availability, quantity, critical dimensions, tolerance requirements, surface finish, tool access, workholding considerations
File consistency, material, quantity, critical dimensions, tolerances, finish and inspection scope.
Restricted tool access, thin-wall movement and tolerances tighter than the function requires.
Clarifications are resolved before quotation, so manufacturing follows confirmed requirements.

SURFACE FINISHING
Surface treatments can be coordinated according to project requirements, and may include anodizing, hard anodizing, bead blasting, polishing, painting, powder coating, passivation, electropolishing, laser marking and black oxide, with heat treatment coordinated where the drawing requires it. Feasibi
Anodizing, hard anodizing, painting and powder coating, with masking requirements identified on the drawing.
Bead blasting and polishing for surface texture and cosmetic requirements.
Passivation, electropolishing, laser marking, black oxide and heat treatment, coordinated per order.

QUALITY & INSPECTION
Finished parts are checked against the confirmed drawing and project requirements, with basic dimensional verification using calipers, micrometers, depth gauges and height gauges. Inspection scope and documentation requirements are reviewed during quotation: requested photographs, recorded dimension
Critical dimensions checked with calipers, micrometers, depth gauges and height gauges.
Inspection records cover the dimensions and requirements agreed in the quotation scope.
Photographs, recorded dimensions and documentation formats are agreed during RFQ.
