About the workshop

An OEM workshop built around CNC machined ABS plastic in China

Rather than selling catalog items, we machine each ABS part to the exact drawing the customer provides, and we keep every major process under one roof.

Drawing-based OEM production

We are an original-equipment manufacturing workshop focused on CNC machined ABS plastic in China. Production starts from the customer's own 2D drawings and 3D models instead of a standard product list, so dimensions, tolerances, threads and appearance always follow your documentation.

Turning, three-axis, four-axis and five-axis milling, drilling, tapping, deburring and inspection are completed in the same workshop. Most ABS parts therefore move through the whole process without being transferred between outside suppliers, which shortens lead time and keeps dimensional relationships consistent.

How an ABS drawing moves through the floor

  • Drawing review: dimensioning, tolerances, wall thickness and internal corners are checked before programming; unclear notes are raised with the customer instead of being guessed at the machine.
  • Machining strategy: sharp tooling, controlled chip evacuation and suitable feeds and speeds keep cutting heat low, so ABS does not melt, smear or develop burrs that are difficult to remove.
  • Secondary work: deburring, edge breaking, tapping, insert installation and surface finishing follow the main machining operation in a fixed sequence.
  • Inspection and packing: critical dimensions are measured, after which parts are cleaned, bagged and packed to survive export transport.
Material behaviour

Why ABS is well suited to precision machining

ABS combines toughness, low weight and clean cutting behaviour, which makes it one of the most practical engineering thermoplastics for machined functional parts.

Impact toughness

ABS resists chipping and cracking both during machining and in final assembly. It absorbs the shocks of snap fits, clips and repeated handling better than more brittle rigid plastics.

Low moving mass

With a density around 1.05 g/cm³, ABS is roughly one eighth the density of steel. Machined ABS components reduce inertia in moving assemblies and make manual handling easier.

Predictable machining

With sharp tooling and correct speeds, ABS cuts cleanly into small chips rather than melting back onto the cutter. Its limited moisture uptake also keeps post-machining dimensional movement low.

Finish flexibility

Machined ABS can be left with a fine matte milled finish, or taken through deburring, polishing, bead texturing and painting. Natural ivory, black and pre-coloured stock are all available.

Machining capabilities

Turning, milling, drilling and tapping in one workshop

The four core processes cover the full geometry range of CNC machined ABS plastic in China, including rotational parts, prismatic housings, precise hole patterns and durable threads.

CNC turning

CNC turning produces rotational ABS parts such as sleeves, bushings, spacers, rollers, pulley blanks, washers and threaded plugs. Facing, outer- and inner-diameter turning, grooving, parting and thread cutting are completed in one setup where the geometry allows.

Parts that also need flats, cross holes or milled slots can be finished with live tooling or transferred to a milling setup on a matched program.

3-axis CNC milling

Three-axis milling handles flat panels, covers, pockets, slots and regular hole patterns on prismatic ABS blocks and plates. It is the most economical route for parts whose features are reached from one or two sides.

Vacuum-style fixturing, soft jaws and double-sided programs are used to keep thin ABS panels flat and free of clamping marks.

4-axis and 5-axis milling

Four-axis indexed milling machines features around a cylindrical part in a single setup, while five-axis simultaneous machining reaches compound angles, curved surfaces and undercuts without re-fixturing.

This keeps a precise relationship between faces that would otherwise accumulate alignment error across several manual setups.

Drilling and tapping

Drilling covers plain holes, stepped holes, counterbores, countersinks and reamed holes, with peck cycles clearing chips from deep holes. Tapping produces internal threads in metric M-series and unified UNC/UNF sizes.

Where a thread must survive repeated assembly, heat-set brass inserts or press-fit bushings replace the cut thread for a longer service life.

Order quantities

From a single machined piece to large-batch production

The same drawing can travel from one prototype to repeated volume campaigns without changing supplier, because programs, fixturing and inspection records are kept.

Single piece and prototype

One machined ABS part is treated as a complete, normal order. A first article confirms fit, function and appearance before any fixturing or volume decision is made, cut directly from bar or plate stock.

Low-volume pilot batch

Pilot batches in the tens of pieces bridge prototype and series production. They support assembly trials and design freeze without committing to large material purchases.

Mid-volume repeat orders

Quantities in the hundreds rely on dedicated soft jaws and saved programs. Monthly or quarterly call-offs are produced against the same documented process, keeping cycle times and appearance stable.

Large-batch production

Campaigns in the thousands spread setup cost across many parts. Planned in-process inspection, batch identification and staged packing keep long production runs traceable from raw material to dispatch.

Material options

ABS grades selected to match the application

CNC machined ABS plastic in China is not limited to a single generic sheet. The grade is chosen from the drawing note, the assembly environment and the mechanical load the part will carry.

General-purpose ABS

The standard choice for housings, covers, panels and general machine components. It balances stiffness and impact resistance and is available in natural ivory, black and customer-specified colours.

Flame-retardant ABS

Flame-retardant grades are selected when an enclosure or cover is expected to slow flame spread. The exact grade follows the drawing or the application note supplied by the customer.

Glass-fibre-reinforced ABS

Glass-filled grades raise stiffness and reduce slow deformation under sustained load, suiting structural brackets, locators and parts that position metal components.

ABS / PC blend

Blending ABS with polycarbonate increases impact strength and heat resistance for parts exposed to higher mechanical loads or warmer operating environments, while remaining machinable with standard processes.

Order process

How a custom ABS order moves forward

A fixed four-step sequence keeps a one-off prototype and a ten-thousand-piece repeat order equally traceable.

01

Drawing review and DFM feedback

Drawings and models are checked for dimension completeness, wall thickness, internal corner radii and tool reach; questions are consolidated before programming.

02

Material and CNC programming

The ABS grade and colour are confirmed, stock is cut to size, and tool paths are programmed with feeds and speeds tuned to thermoplastics.

03

Machining and finishing

Turning, milling, drilling and tapping run to the planned setup sequence, followed by deburring, edge breaking and any agreed surface finishing.

04

Inspection and packing

Dimensions are checked with 2D and 3D measuring equipment, then parts are cleaned, bagged and packed in layers suitable for export transport.

Quality process

Inspection logic from raw stock to packed parts

Quality control is built around the drawing itself: every check references a stated dimension rather than a general impression.

Material confirmation

Grade, colour and batch information are recorded before cutting. Customer-supplied material is accepted, labelled and tracked as a separate stream.

First-article check

The first completed part receives a full dimensional review against the drawing before the rest of the batch continues on the machine.

In-process control

Key dimensions are rechecked after each major operation, and cutter wear is watched closely on long runs to stop drift before it accumulates.

Final inspection and packing

A final visual and dimensional check is followed by cleaning, individual bagging and layered protective packing for transport.

Common questions

Frequently asked questions about machined ABS orders

Practical questions buyers raise when placing CNC machined ABS plastic in China with a drawing-based OEM workshop.

Do you work only from customer drawings?

Yes. Every part is built to the customer's 2D drawings and 3D models rather than taken from a catalog. PDF drawings paired with STEP or IGES models are the clearest starting point.

Is there a minimum order quantity?

There is no fixed MOQ. A single machined ABS prototype is a normal order, and the same drawing can later move into low-, mid- or high-volume production.

Which ABS grades can be machined?

General-purpose ABS, flame-retardant grades, glass-fibre-reinforced ABS and ABS/PC blends can all be machined. Grade and colour are confirmed before any stock is cut.

Can metal inserts be integrated?

Yes. Heat-set threaded inserts, press-fit bushings and dowel pins can be installed during secondary operations, giving threads and locating points a longer service life.

How are burrs and edges controlled?

Sharp tooling, conservative feeds, controlled spindle speed and systematic hand deburring keep edges clean. Edge breaks and chamfers always follow the drawing notes.

How is consistency kept on repeat orders?

Tool paths, fixturing, material grade and inspection points are recorded for each part, so later batches reproduce the dimensions and appearance of the first approved run.

A single process line for CNC machined ABS plastic in China

When sourcing CNC machined ABS plastic in China, the practical difference is made on the shop floor: sharp tooling, sensible fixturing, disciplined measuring and stable communication around the drawing. This workshop keeps turning, three-axis, four-axis and five-axis milling, drilling, tapping and inspection under one roof.

As a result, a single ABS prototype and a ten-thousand-piece repeat order follow the same drawing logic, the same inspection sequence and the same documented process, from the first cut in solid ABS stock to the final labelled package ready for export.
