Custom Machined Plastic Parts for the Energy Industry

Great Plastics manufactures custom engineering plastic components to customer drawings for energy equipment and industrial systems. Material selection and machining requirements are reviewed against operating temperature, mechanical loads, wear, chemical exposure and dimensional requirements.

Plastic Components for Energy Equipment

Source oil and gas plastic components for fluid control, rotating equipment and electrical assemblies. Specify the fluid, motion and electrical duty behind each part.

Valve Seats & Sealing Parts

PEEK valve seats, backup rings and stem guides made to your drawing. The sealing profile must hold under compression while resisting the process fluid. Grade choice also affects creep, contact wear and the finish at the sealing interface.

Bushings, Sleeves & Wear Rings

Components for shaft guidance, sliding contact and running clearances in pumps and rotating equipment. PEEK, PPS and PAI offer different load and wear options. Abrasive particles, dry running and the mating surface can change the grade choice.

Electrical Insulators & Supports

Connector bodies, pin carriers, spacers and equipment supports in PEEK, PEI, PPS or PI. Pin spacing, wall sections and mounting holes matter alongside dielectric performance. Conductive fillers require a different specification from insulating grades.

CNC Milling, Turning & Machining Capability

Great Plastics combines plastic-material supply with CNC machining. Your part geometry determines whether milling, turning or combined operations provide the better route.

Fraisage CNC

Pockets, mounting faces, bolt patterns and intersecting holes in blocks and plates. Three-axis vertical machining provides a nominal envelope up to 1500 × 800 × 500 mm. Tool access and fixture clearance determine how much of that envelope your part can use.

Tournage CNC

Seats, stepped bores, sleeves, grooves and threaded profiles from round stock. Nominal turning capacity is up to Ø431 × 990 mm. Long, thin walls need support to limit deflection. Chucking length and stock availability reduce the usable part size.

Combined Turning & Milling

Dual-spindle turn-mill equipment brings flats, radial holes and off-axis features onto turned parts. Fewer transfers can help preserve the relationship between the bore, outside diameter and secondary features. Feature access and tooling still determine the setup.

Les enveloppes d'usinage ne garantissent pas les dimensions de la pièce finie. Le matériau, la forme de la pièce brute, le système de serrage et l'accès à l'usinage déterminent les dimensions réalisables pour votre plan.     Capacités d'usinage CNC des matières plastiques

Complex Features. Controlled Fits

Critical tolerances belong at the sealing, sliding and assembly interfaces. Feature-specific tolerances are agreed from your drawing, with the material and measurement conditions defined.

Sealing Faces & Concentric Bores

Sealing Faces & Concentric Bores

A seat profile, groove depth and bore-to-OD runout each control a different part of the fit. Thin sealing lips can move under clamping.

Dimensional acceptance:

Check the agreed features in the defined material and measurement conditions.

Operating fit:

Thermal expansion, moisture and creep can change clearances under heat and sustained load.

Mounting Holes & Ribbed Supports

The representative bracket geometry combines mounting bores, ribs and recessed faces. Datum choice connects the hole pattern to the mating surface. Internal radii and tool reach constrain deep pockets; thin ribs need support during machining.

Windows & Slender Walls

PI cage machining involves open windows, thin webs and flanged ends. Cutter access and machining sequence control wall deflection, while cross-drilled passages must allow burr removal. Enclosed features may require redesign.

Choix des matériaux

Material Options for Your Operating Conditions

Material fit depends on chemical exposure, temperature, load, motion and electrical duty together. Match the exact grade to your service conditions; a polymer family name alone does not establish suitability.

Matériau Ajustement des composants Choix des notes et limites
PEEK Valve seats, backup rings, bushings and connector bodies. Unfilled, glass-filled, carbon-filled and bearing grades serve different duties. Fillers change stiffness, wear and electrical behavior. Strong oxidizers need specific compatibility evidence.
PPS Fluid-contact parts, guides and dimensionally stable supports. Unfilled, glass-filled, carbon-filled and wear-modified grades differ. Thin edges and notches need care. Chemical compatibility depends on the complete formulation and exposure conditions.
Î.-P.-É. Electrical housings, pin carriers and dry-side supports. Useful where stiffness and insulation matter. Fluid compatibility and stress cracking can limit exposed parts; specify the electrical grade.
PAI Loaded bushings, thrust parts and wear components. Moisture conditioning affects dimensions. Hot water, steam and amines need particular review. Specify the filler and conditioning state.
PI Hot supports, insulating spacers and specialized wear parts. Grade, atmosphere and contact conditions govern suitability. Moisture, hot-water exposure and fillers can change the working fit.

Carbon-filled grades may be electrically conductive. A room-temperature clearance or chemical rating does not establish performance under heat, pressure and sustained load.

Comment un projet avance-t-il ?

Du prototype à la production en série

Develop the part in its intended material, then carry the accepted geometry into production. Great Plastics supports prototypes, small batches and repeat orders for energy equipment components.

1

Prototypage et validation des applications

Examinez le plan, les matériaux et les caractéristiques essentielles. Testez les prototypes usinés pour vérifier leur ajustement et leurs performances dans des conditions réelles d'exploitation.

2

Production en petites séries

Utilisez l'échantillon approuvé, la révision du plan, la nuance du matériau et les dimensions clés comme références pour la production.

3

Réapprovisionnement

Respecter les exigences approuvées en matière de matériaux, de plans et de contrôles. Valider à nouveau les modifications apportées à la géométrie, aux matériaux de remplissage ou aux conditions d'exploitation.

Questions des acheteurs

Foire aux questions

Yes. Send the drawing or CAD model with the fluid, temperature, load and electrical requirements. Great Plastics can review candidate materials with your part geometry. The quote can then define the grade and feature-specific acceptance requirements.

A drawing is the best starting point. If you only have a sample, photographs and operating history help identify wear and interfaces. A worn sample may no longer show the original dimensions or clearances; those features need an agreed reference.

No. Qualification applies to a defined grade, service environment and test scope. A material family name or dimensional report does not establish compliance with your equipment specification. Identify the required standard and approval evidence with your enquiry.
