At Asmech, we have been creating bespoke conveyor and handling systems since 1995. We are able to design, manufacture, install and service all the products and solutions in our range. Our conveyor systems are made from many different materials, the conveyor belts often have three layers. Steel conveyor belts are chosen when a high strength class is needed. Cotton, nylon and polyester being commonly selected for low strength classes. Many belts are made from PVC and rubber materials.

Plastic Wearbed materials

Plastic wearbeds are made with polyethylene, a semi crystalline thermoplastic with high toughness. Their chemical resistance offers superb impact resistance, high tensile strength, and high resistance to a wide range of chemicals including acids, detergents and hot water. It fully complies with the FDA regulations making it an excellent solution for food contact parts. It has been widely used in a wide variety of applications and industries due to its cost effectiveness and excellent machinability.

PET (Polyethylene Terephthalate) is one of the most widely used engineering plastics, together with POM-C and Nylon. Its excellent mechanical properties make it suitable for precision parts. It provides high tensile and mechanical strength, extreme hardness and excellent dimensional stability. The product has a very low coefficient of friction making it an ideal choice for wearing components.

Nylon 66, obtained by the polymerisation of hexamethylenediamine and adipic acid. It’s one of the oldest engineering plastics, having been created in the USA in 1930. Due to its origin it’s widely used in the American and English markets. In comparison to nylon 6 it’s stiffer and tougher but more brittle. It’s advisable to use PA66 instead of PA6, when a higher stiffness is required to the detriment of resilience. It can be easily machined on automatic machine tools.


Wear resistance: it is good even in demanding environments.
Self-lubricating: the friction coefficient is low and generally for sliding application it does not require lubricators.
Toughness: very high tensile stress and compressive strength. Its toughness is higher than that of Polyamide 6.
Machining on automatic machine tools is shown to be easy as the shavings break thanks to its higher toughness.
Ageing resistance and weatherproof.
It’s resistant to alkali, inorganic compounds and solvents.
In some cases it can be used in contact with food.


It is hygroscopic, even if to a lesser extent than PA6.
It absorbs moisture in time and consequently the mechanical features and the final dimensions will change.
Use in the electrical field is to be avoided as the electrical features change with the moisture content.


Due to its higher stiffness than PA6, it’s used for mechanical applications when this feature is more important than that of shock resistance, particularly suitable for:

Anti-wear guides

Stainless Steel

Stainless steels are a group of corrosion resistant steels that contain a minimum of 10.5 % chromium. There are other steels, including some tool steels that also contain these levels of chromium. The difference between these steels and stainless steels is that in stainless steels the chromium is added principally to develop corrosion resistance. The European standard for stainless steels, EN 10088 (published in the UK as BS EN 10088) defines stainless steels as steels with a minimum of 10.5% for use in applications where their corrosion resistance is required. Many commercially available stainless steels contain more than this minimum level of chromium and, in addition, contain varying amounts other alloying additions including nickel, molybdenum, titanium, niobium etc. These additions are made, not only to enhance the corrosion resistance of the steel but also develop other properties, such as mechanical strength, hardness, toughness, magnetic properties etc. or to change working characteristics including formability, machinability and weldability.

Stainless steels can also be used in heat resisting and cryogenic applications as they also have excellent oxidation resistance. These particular steels generally have enhanced chromium levels to improve their heat resisting properties. They are covered by the BS EN 10095 standard. The behaviour of the various stainless steels during manufacture, fabrication and in-service not only depends on their chemical compositions, but also on the design and surface finish of the manufactured items. Careful selection of the most appropriate steel grade, design and surface finish are vital to the successful application of stainless steels.

Chains: Flight top and Gripper chains

Austenitic Cr-Ni cold rolled austenitic stainless steel

Non-magnetic stainless steel alloy, superior resistance to stress-corrosion cracking. It guarantees the best corrosion resistance to withstand chemical attack. It offers very good wear resistance, due to work hardening and homogeneous chemical structure.

Ferritic stainless steel cold rolled stainless steel

High chromium, magnetic stainless steel that has a low carbon content. Good wear, mechanical and corrosion resistance. Commonly used in food and beverage applications.

Maintenance free carbon steel

Roller chains for maintenance free applications.

The pin is case hardened with a hard surface plating to provide excellent resistance to elongation and corrosion. The ‘heavy wall’ sintered bushing is impregnated with USDA H1 food approved high performance lubricant for increased wear performance. No need for addition lubrication in situ. Solid rollers and side plates have a galvanically coated anti corrosion treatment.

Ultra Performance Acetal Resin

DuPont™ Delrin® Ultra Performance special homopolymer acetal resin. Particularly suitable for applications where low coefficient of friction and contained dusting are needed.

Superior Grade of Acetal Resin (DK2 )

Delrin® acetal resin reinforced with Kevlar®. Developed with DuPont™, able to reach the lowest coefficient of friction with maximum wear resistance. Thanks to the superior properties of the chain, the usage of lubricants can be drastically reduced or even eliminated without losing performance in conveyor applications.

Thermoplastic Rubber

Special Thermoplastic rubber with hardness of 50 ShA and optimum wear resistance that guarantees exceptional product grip in inclined/declined conveyors and elevators/lowerators, extending life without losing elasticity.

EPDM Rubber

For gripper chains. EPDM rubber with hardness of 60 ShA guarantees excellent grip and high temperature resistance. Fingers and materials designed for exerting an ideal and not excessive force for each specific application. Special rubber material, extends life without losing elasticity. Fingers are available in a range of widths and lengths.

PU Belting

Used in a range of food industries, most commonly meat, fish and confectionery. Our standard belt types include 1 and 2 ply in white and blue, all with very good anti-fray and hygiene properties to HACCP regulations. The new 2 ply blue PU Belting has been very successful since its launch in 2004 due to its unique top cover giving excellent release, anti-cracking and low temperature properties. Full details upon request. A polyurethane is polymer composed of a chain of organic units joined by carbamate (urethane) links.

Typical characteristics for a PU belt are high flexibility even at low temperatures, good abrasion resistance and good resistance to fats and oils. They are also odor-free (no migration of plasticizers). They are typically not resistant to hot water (steam) hydrolysis and are not resistant to chlorine and to many organic solvents.

PVC Belting

All PVC belting is FDA and USFDA approved (data sheets can be supplied on request). Our range is too vast to list, so please contact our sales office for details. Polyvinyl chloride, commonly abbreviated to PVC, is the third most widely produced plastic after polyethylene and polypropylene. Polyvinyl chloride is produced by polymerization of the monomer vinyl chloride. Typically, PVC belts offer good chemical resistance (including to chlorine), hydrolysis-resistant (resistant to hot water and steam) and good UV resistance, however, they generally offer low flexibility at low temperatures, limited abrasion resistance and limited resistance to solvents, oil and grease.

Profiles & Sidewalls

Conveyor belts with profiles are used for the inclined and declined conveying of bulk goods and small pieces. To contain goods on the sides when conveying bulk goods, sidewall profiles are used often in conjunction with lateral profiles.

Our profiles offer a high level of resistance to oils and grease, as well as cleaning agents and disinfectants. They are available in a wide range of thickness, height, width and pitch and and can in some cases be supplied as roll material. Profiles are available in PVC, PU and Polyester. These have been manufactured to conform to ISO 21181:2005.


It is possible to maintain very narrow tolerances for practically any pattern of perforations (Belt material with perforations can not be used for form-fit transmission of power.)

Belt edge sealing

Belt edge sealing prevents oil, grease, water, foreign bodies and bacteria from penetrating the belt. At the same time, it increases the service life of the conveyor belt. Our anti fray belts mean virtually no fluff forms on the edges of the belt. A special type of fabric and weave as well as an enhanced filament length, ensures that no problems are caused by the unsealed belt edges.

Types of splices

The splicing method appropriate for individual applications is dependent on the belt types used and the prevailing operating conditions. In addition to splice reliability, flexibility of the splice and the effort required for fabrication are decisive criteria for the selection of the splicing method. Detailed instructions for all splicing procedures are available on request.


A hot-pressed splice provides the highest durability and flexibility. Following types are available:

Z-splice Meets the most rigorous of requirements for uniformity of thickness. Very flexible splice, required particularly for knife edge belts. Standard splice for 1 and 2-ply belt-types.

Stepped Z-splice Properties comparable to those of the Z-splice. Also suitable for rugged operating conditions (e.g. soiled drums). Possible for various 2 and 3-ply belt types.

Wedge splice Splice type for solid-woven fabric and NOVO types.

Stepped overlap splice Especially for 2 and 3-ply belt types with duroplastic coatings


It is possible to cold-press wedge or stepped overlap splices in independent fitting repair jobs on site. Please note that such splices have limited strength and flexibility
