PMTEC supplies paper mill spare parts and wear components across the complete fiber line, from waste paper intake to the finished roll. Components are supplied to drawing, to sample, or to measured survey where original documentation no longer exists.
This section is organized in five categories, following the process.
Product categories
| Category | Process boundary | Main component groups |
| Stock Preparation | Bale intake → machine chest outlet | Pulper rotors and screen plates, screen baskets and rotors, cleaner cones, fractionation screens, refiner plates, thickening and dispersion parts |
| Paper Machine | Machine chest outlet → finished roll | Fan pump and headbox components, dewatering elements, suction roll and shoe press parts, dryer syphons and spoiler bars, size press and calender parts, broke and white water components |
| Rolls & Roll Service | All positions | Complete rolls, roll covers, recovering, grinding, dynamic balancing |
| Clothing & Wear Parts | All positions | Forming fabrics, press felts, dryer fabrics, specialty fabrics, doctor blades |
| Pumps, Piping & Instrumentation | All positions | Stock and fan pumps, vacuum systems, valves, piping, sealing, transmitters |
Selection basis
Four inputs determine component specification. All four are required before a technical quotation can be issued.
| Input | Determines |
| Furnish and contaminant load | Material class and hardfacing requirement |
| Operating conditions — consistency, flow, temperature, pH, pressure, speed | Mechanical and chemical duty |
| Process objective | Geometry: aperture, bar pattern, cover type |
| Required service interval | Whether component life aligns with planned shutdowns |
Component life is compared on cost per operating hour, including changeover labour and lost production, not on unit price.
Material classes
| Class | Application |
| High-chromium cast iron | Abrasive duty — pulper rotors, wear plates |
| Alloy steel with hardfacing | High abrasion and impact — rotors, screw flights, reject handling |
| Stainless 304 / 316 | General stock and white water service |
| Duplex / super duplex | High chloride, low pH, closed water loops |
| Alumina ceramic | Severe abrasion — cleaner cones, element covers, suction box covers |
| Polyurethane | Impact-prone positions, roll covers, press belts |
| UHMWPE / composite | Low-friction, fabric-contact surfaces |
Closed water systems concentrate chlorides and raise temperature. Where a component that previously lasted begins to fail, verify water chemistry before changing supplier or material.
Supply process
Enquiry
|
part list, drawings, samples or photographs
Technical evaluation
|
application review, material and geometry proposal
Drawing confirmation
|
manufacturing drawing issued for customer approval before production
Manufacturing
|
through qualified manufacturing partners
Inspection
|
dimensional and material verification; customer and third-party inspection accepted at the manufacturing site
Delivery
|
export packing and documentation
*Where no drawing exists, components are reverse engineered from a sample or from measured dimensions. Worn surfaces are not used as reference surfaces.
Frequently asked questions
Can spare parts be supplied without an original drawing?
Yes. Components are identified from photographs, samples, measured dimensions or machine data, and a manufacturing drawing is issued for confirmation before production begins.
How is quality verified before shipment?
By dimensional inspection, material verification and documentation review. Customer and third-party inspection at the manufacturing site is accepted.
Can a component be upgraded rather than duplicated?
Yes — through material change, hardfacing, surface treatment or geometry revision. Any change is confirmed on drawing before production.
What lead times apply?
Standard wear parts held in production programmes are short-lead. Made-to-drawing castings, roll bodies and large fabricated items depend on pattern availability, machining capacity and inspection scope.
Which machine brands are covered?
Compatible components are supplied for major international and Chinese paper machinery brands.
