From prototypes to repeat production, BatchMach Precision brings together two ISO-certified CNC factories, practical machining expertise, and dimensional inspection to deliver custom parts built to your drawings.
Rigid PVC is relatively stiff and machinable, but excessive cutting heat can soften the material and produce melted burrs or dimensional changes. PVC Type I, Type II, clear PVC, and CPVC also differ in impact strength, service temperature, chemical compatibility, and stock availability. BatchMach Precision confirms the material grade and operating requirements before production.
Our 3-axis, 4-axis, and horizontal machining capabilities support PVC parts with pockets, holes, slots, sealing surfaces, and multi-sided features. Sharp tools, adequate chip clearance, and controlled cutting parameters help limit heat buildup and maintain clean edges.
CNC turning is used to manufacture cylindrical PVC parts from rod or tube, including outside diameters, bores, grooves, threads, and sealing features. BatchMach Precision controls chuck pressure, tool condition, cutting heat, and part support to reduce deformation, melted burrs, and damage to thin-wall sections.
Five-axis machining is suitable for PVC components with angled holes, multiple sealing faces, complex contours, or strict positional relationships. Reducing unnecessary setups helps maintain feature alignment and limits repeated handling of clear or appearance-critical surfaces.
BatchMach Precision supports one-off prototypes, replacement parts, low-volume batches, and repeat production with no MOQ. For production orders, we can optimize stock selection, workholding, toolpaths, and machining sequences after the PVC grade, quantity, tolerances, and inspection requirements are confirmed.
Rigid PVC is used for machined components that require stiffness, electrical insulation, low moisture absorption, and resistance to corrosion or selected chemicals. Common applications include valve and pump components, manifolds, electrical insulators, laboratory fixtures, equipment panels, spacers, and fluid-handling parts.
PVC grades should not be treated as interchangeable. Type I PVC is commonly selected for general industrial components, while Type II provides improved impact resistance. Clear PVC is used where visibility is required, and CPVC is considered for higher operating temperatures. BatchMach Precision reviews the material grade, chemical exposure, service temperature, wall thickness, fits, and drawing requirements before production.

*Clear PVC and CPVC values represent specific commercial stock grades. The CPVC temperature value is a published service-temperature rating rather than an HDT result, so it should not be compared directly with the other rows.
Keeps costs and lead times low while preserving the original machined dimensions.
Removes sharp edges and burrs while reducing visible machining marks.
Improves surface smoothness, gloss, and the visibility of selected clear PVC areas.
Creates a uniform matte texture, reduces glare, and makes light tool marks less noticeable.
Adds color, provides light blocking, and applies logos, scales, warnings, or part identification.
The values below are practical starting points for rigid PVC and CPVC parts, not universal machining limits. Final dimensions should be reviewed against the material grade, part size, workholding method, and tolerance requirements.
| Design Feature | Recommended Value | Reason |
|---|---|---|
| General wall thickness | ≥1.5 mm preferred; review walls between 0.8 and 1.5 mm | Thicker, uniform walls reduce clamping distortion, vibration, and edge chipping |
| Tall thin walls | Keep the height-to-thickness ratio ≤10:1 | Excessively tall walls can deflect under cutting forces and clamping pressure |
| Deep holes | Keep hole depth ≤6× diameter; retract every 3–4× diameter for chip clearing | Trapped chips increase frictional heat, dimensional variation, and melted burrs |
| Deep pockets | Keep pocket depth ≤4× cutter diameter | Deeper pockets require longer tools, increasing vibration, chip-control problems, and sidewall marks |
| Internal corner radii | Use R≥1.0 mm and preferably at least one-third of the pocket depth | Larger radii allow more rigid cutting tools and reduce stress concentration |
| Threads | Use M3 or larger where possible; provide 1.5–2× diameter engagement | Larger thread forms and sufficient engagement reduce stripping and edge damage |
| Hole-to-edge distance | Keep the hole center at least 1.5× the hole diameter from the edge | Sufficient surrounding material reduces cracking and breakout during drilling |
| Large flat surfaces | Review surfaces over 300 mm or flatness requirements below 0.10 mm | Stock stress, workholding, and temperature changes can affect final flatness |
| Dimensional measurement | Use 20°C as the reference temperature and measure after unclamping | Thermal expansion and elastic recovery can affect measurements taken immediately after machining |
PVC and CPVC are both available as machinable rigid plastic stock, but they should not be treated as interchangeable. Standard rigid PVC is generally selected for cost-effective components used at moderate temperatures, while CPVC is considered when higher operating temperatures are expected.
| Comparison | Rigid PVC | CPVC |
|---|---|---|
| Typical published service temperature | Around 60°C, depending on grade | Around 85°C, depending on grade |
| Chemical resistance | Suitable for many acids, alkalis, and industrial fluids | Often selected for elevated-temperature chemical and fluid service |
| Material cost | Generally lower | Generally higher |
| Stock availability | Broad availability in sheet, rod, tube, and block | More limited sizes and grades |
| Machining behavior | Machines well with sharp tools and controlled cutting heat | Also machinable, but material cost makes process planning and scrap control more important |
| Common machined parts | Manifolds, insulators, covers, fixtures, valve components, and equipment parts | Hot-fluid components, chemical-handling parts, manifolds, valve components, and process-equipment parts |
BatchMach Precision machines both rigid PVC and CPVC parts with no minimum order quantity. Final material selection is based on the drawing, operating conditions, required documentation, stock availability, and order quantity. Chemical resistance and temperature limits must be verified against the selected manufacturer’s grade—not the generic material name alone.
Choose rigid PVC when the component operates within the material’s temperature range and the project prioritizes rigidity, chemical compatibility, stock availability, and cost. It is a practical choice for prototypes, replacement parts, and production components used in moderate-temperature environments.
Choose CPVC when the operating temperature is too high for standard PVC or when the application involves heated chemicals or process fluids. The exact fluid, concentration, pressure, temperature, and exposure time should be reviewed before the grade is confirmed.

BatchMach Precision develops the inspection plan around the approved drawing, with particular attention to mating dimensions, hole positions, threads, sealing features, and thin-wall deformation.
Before production, we verify whether the specified material is PVC Type I, PVC Type II, clear PVC, or CPVC. We also confirm the color, stock form, critical tolerances, datums, threads, and surface-finishing requirements. When material documentation is required, the applicable records are confirmed before purchasing and production.
ZEISS CONTURA and Hexagon CMMs, vision measurement systems, TESA height gauges, and Mitutoyo precision measuring tools are used to inspect bores, hole positions, flatness, parallelism, profiles, and mating dimensions. Distortion-sensitive features can be rechecked after the part has been released from the fixture and allowed to stabilize.
Before shipment, we inspect parts for burrs, chipped edges, scratches, heat-related surface marks, and defects around threads, sealing grooves, and passage openings. Specified viewing areas on clear PVC parts are also checked. Parts are released for shipment only after the quantity, critical dimensions, and required surface conditions have been verified.
Yes. Rigid PVC sheet, rod, tube, and block can be CNC milled, turned, drilled, threaded, and 5-axis machined. BatchMach Precision controls tool condition, cutting heat, chip evacuation, and clamping pressure to reduce melted burrs, edge chipping, and deformation.
We machine rigid PVC Type I, impact-modified PVC Type II, clear PVC, and CPVC. These materials differ in rigidity, toughness, transparency, temperature capability, and chemical compatibility. The exact grade is confirmed according to the drawing, operating conditions, and stock availability.
Rigid PVC is generally suitable for cost-conscious components operating at moderate temperatures. CPVC is considered for heated fluids and higher-temperature chemical environments. Selection should account for the chemical, concentration, temperature, pressure, and exposure time—not simply the material name.
BatchMach Precision can hold critical PVC part tolerances down to ±0.005 mm.
Yes. We machine internal and external threads, precision bores, O-ring grooves, sealing surfaces, intersecting holes, and internal passages. The RFQ should identify the thread standard, fit requirements, seal specifications, and critical surfaces.
Yes. BatchMach Precision machines clear PVC inspection windows, guards, covers, and visible fluid-handling components. Selected surfaces can also be sanded or mechanically polished. Required viewing areas and appearance standards should be identified on the drawing.
We use sharp tools, controlled cutting parameters, effective chip evacuation, and low-stress workholding selected for the PVC grade and part geometry. Thin-wall parts or components requiring substantial material removal may be machined in stages to reduce heat buildup and movement after unclamping.
Available options include as-machined, deburring, manual sanding, mechanical polishing, sand blasting, painting, and printing. The finish is selected according to appearance, transparency, dimensional requirements, and operating conditions.
Yes. BatchMach Precision has no minimum order quantity and supports one-off prototypes, low-volume batches, and repeat production. Simple projects can be delivered in as fast as one day after the drawing, material, and inspection requirements are confirmed.
