Where scrapers work
Where plastic scrapers are used
Each job asks something different of the edge, the load and the plastic. Find the one closest to yours.
-
Conveyor belt cleaning

- What matters
- Contact angle, belt speed and splices.
-
Rolls and doctor blades
- Removes
- Residue, ink or coating on a turning roll.
- What matters
- An even edge across the roll face, and chemical resistance.
-
Kettles and mixers
- Removes
- Product building up on a vessel wall.
- What matters
- Food-zone requirements, cleaning and fragment detection.
-
Tanks and screens
- Removes
- Sludge and solids in water-treatment equipment.
- What matters
- Constant wet service, abrasion and chemicals.
Scraper anatomy
Edge, angle and holder work together
A scraper only cleans while the right part of the edge meets the surface at the right angle and pressure. These are the details that define your blade.
- Holder The type of holder or bracket the blade sits in.
- Clamp zone Where and how the blade is clamped, with any holes or slots.
- Working edge Edge shape, bevel and thickness at the tip.
- Contact angle The angle the edge meets the surface at.
- Moving surface What it cleans: the material, finish, speed and direction.
- Wear patch Where and how the old blade wore.
Plastics for scraper blades
Common choices, and why
- UHMW Abrasion resistance and low friction. A common choice for food and water-treatment scrapers.
- Acetal A stiffer, more stable edge.
- PTFE Release and chemical resistance. Watch for creep under constant load.
- PEEK For heat, steam and harsh chemicals.
- Nylon Strong and wear-resistant, once moisture uptake is allowed for.
- Detectable grades Metal- and X-ray-detectable grades for lines with inspection systems.

Choosing a blade type
Is a machined plastic blade right?
Plastic suits many scrapers, but not every one. Here’s an honest guide to where it fits.
A good fit
- Gentle on the surface
- Plastic is softer than metal against rolls, belts and vessel walls.
- No rust
- Unaffected by washdown and wet service.
- Detectable options
- Metal- and X-ray-detectable grades for food lines.
- An exact edge and hole pattern
- Machined to match your holder and contact angle.

Yes. Metal- and X-ray-detectable grades are available. They work with different inspection systems, so tell us which your line uses.
Food-contact documentation is available for the grades used in food zones. Tell us what your line requires and we’ll quote the right grade.
We hold ±0.002" to ±0.005" on critical dimensions, depending on the plastic. We review your drawing and confirm the critical dimensions with your quote.
Yes. Specifications and CAD files are kept on file, so replacement blades match the last batch. Many buyers order spares to keep on hand.
Timing depends on the blade, plastic and quantity, and comes with your quote. For an emergency breakdown, ask about our expedited service.
