What “Plastic Parts Machined for Packaging Machinery” Means to Us
Packaging machines run fast, clean, and continuously. We machine custom plastic parts that help you change formats quickly, handle products gently, reduce wear and noise, and maintain food safety and uptime. Whether you’re building a new filler, capper, labeler, cartoner, case packer, or upgrading a conveyor line, we turn your 2D/3D data—or matched samples—into reliable, repeatable parts.
Typical Packaging Components We Machine
Product Handling & Change Parts
- Feed screws (timing screws), star wheels, indexing discs, pocket plates
- Lane dividers, guides, funnels, chutes, pushers, paddles, centering guides
- Pucks, nests, carriers, fixtures for bottles, vials, jars, pouches, cartons
Conveying & Wear Parts
- Wear strips, guide rails, chain guides, corner tracks
- Rollers, idlers, bushings, slide blocks
Filling & Capping Accessories
- Nozzle spacers, drip trays, drip rings, seals, gaskets
- Cap sorting rails, escapements, chute liners
Inspection & Guarding
- Clear guards, machine windows, light‑transmitting covers and sensor blocks
- Insulating plates, shields, non‑marking bumpers, pads
Fluid Handling & Chemical Contact
- Manifolds, valve seats, pump plates, corrosion‑resistant components
Custom Tooling
- Jigs and fixtures for assembly, test, and line setup
- Locating plates, nests, clamps, and setup aids
Send drawings or a physical sample—we can reverse‑engineer form/fit and machine replacements or improvements.
Recommended Materials for Packaging Equipment
| Application Category | Material | Key Properties |
|---|---|---|
| Low‑friction wear and guides | UHMW‑PE, POM/Acetal (Delrin), PET (PET‑P) | Excellent sliding wear, dimensional stability, low moisture absorption |
| Food contact & chemical resistance | POM, PET, UHMW‑PE, PTFE, PVDF | High chemical resistance, FDA‑compliant grades available, low friction |
| Higher temperature / CIP/SIP | PPS, PPSU, PEI (Ultem), PEEK | High heat and chemical resistance for aggressive cleaning |
| Impact‑resistant or transparent guards | PC (polycarbonate), PMMA/Acrylic | Tough, clear, good optical clarity |
| Specialty grades on request | FDA/EU compliant, detectable, antistatic, flame‑retardant, reinforced | Application‑specific compliance and performance |
We can advise on trade‑offs between wear, stiffness, moisture uptake, temperature limits, and cost. Material certificates provided upon request.
Machining Capabilities for Packaging Parts
Processes & Features
- CNC milling, turning, drilling, tapping, threading, slotting
- Pockets, undercuts, keyways, tight‑fit bores, press‑fit features
- Custom thread forms in plastics
- Cleanly deburred edges and functional surface finishes for sliding/wear
Typical Tolerances
- POM/PET: as tight as ±0.05–0.10 mm on small–medium features
- Nylon/UHMW‑PE: ±0.10–0.20 mm typical
- Threads/fits: per standard or custom class
- Environmental factors accounted for (moisture, temperature)

Design Tips for Packaging Plastics
Use generous corner radii and edge breaks to reduce stress concentrations.
Avoid sharp internal corners—specify reliefs or radii suitable for tools.
Specify realistic tolerances per polymer and environmental conditions.
For sliding interfaces, combine low‑friction plastics with adequate lubrication (if allowed).
Plan for thermal expansion and moisture uptake (e.g., Nylon vs. Acetal/PET).
Define contact surfaces and wear allowances to improve service life.
We’re happy to review your CAD and propose tweaks that improve manufacturability and durability.

Frequently Asked Questions
Can you machine from a sample?
Yes. We can measure your sample and reproduce the part, with improvements if desired.
Do you supply food‑contact compliant materials?
Yes. We can source FDA/EU compliant grades as specified and provide material certificates upon request.
What’s a typical lead time?
Prototypes: often 7–15 days from order and material availability. Production: depends on part complexity and batch size. We confirm lead times with each quote.
Minimum order quantity?
We support one‑offs for trials to repeat/low–medium volume production.
Can you add markings or part IDs?
Yes. We can add simple engraved marks or IDs per your drawing.
Can you prepare features for inserts?
We can machine bores/shoulders for heat‑set or press‑fit inserts per your specification. Installation can be discussed case‑by‑case.
