Custom Scraper Conveyor Chain Manufacturer

Frequently Asked Questions About Custom Scraper Conveyor Chain Parts

1. What scraper conveyor chain components does SIMIS manufacture?

SIMIS supplies OEM forged chain links, connecting forks, chain joint pins and bushings, scraper flights, replaceable wear parts, sprocket blanks and related metal attachments. Components are manufactured to customer drawings rather than offered as universal replacements for every conveyor. Suitable production routes include closed-die steel forging, casting and wear-resistant plate fabrication.

2. Can SIMIS produce closed-die forged scraper conveyor links?

Yes. Closed-die forging is a core manufacturing option for compatible tensile chain links and clevis-type connectors. A heated steel billet is formed in shaped dies to produce the required profile. Suitable materials include customer-specified 40Cr, 42CrMo or other alloy steels. Chain pitch, joint geometry, material condition and any specified mechanical requirements follow the approved OEM drawings.

3. Which scraper conveyor parts can be cast?

Suitable scraper flights, sprocket blanks, mounting bodies and replaceable wear elements can be produced through approved sand casting or other casting processes. High-chromium white cast iron and manganese steel may be used for specific abrasion or impact conditions. These materials should not automatically replace forged, tension-loaded chain links. Some flights are more appropriately made from abrasion-resistant steel plate.

4. What materials are available for scraper conveyor components?

Materials include forged carbon and alloy steels such as 40Cr, 42CrMo and AISI 4140; customer-specified carburizing steels for selected joint parts; cast steel and wear-resistant cast iron for certain scraper bodies; abrasion-resistant steel plate for fabricated flights; and suitable 304 or 316 stainless steel components. Each material is matched to the particular part and its approved service requirements.

5. What information is required for an OEM scraper chain quotation?

Provide the component drawing or CAD model, required part type, material grade, critical dimensions and estimated order quantity. For links, include chain pitch and pin or joint geometry; for flights, include width, height and mounting details. Identify the conveyed material and whether you need forged blanks, castings or finished parts. Email drawings to info@simis-group.com.

OEM Custom Scraper Conveyor Chain and Metal Parts Manufacturer

Custom scraper conveyor chain parts are used to move coal, ore, ash, cement, fertilizer and other bulk solids through an industrial conveying trough. In a typical system, articulated chain links transmit pulling force, scraper flights push material, and drive sprockets engage the chain through matched joint geometry.

SIMIS supplies forged alloy steel scraper chain links, connecting forks, joint pins, scraper flights, cast wear parts and sprocket-related components to customer drawings. Our focus is the manufacture of specified metal parts, rather than supplying or certifying a complete scraper conveyor installation.

Manufacturing routes differ by component. Closed-die steel forging is relevant to suitable load-transmitting links and connectors. Cast steel and selected wear alloys can be used for appropriately specified scraper bodies and abrasion-contact elements. Plate cutting and forming are additional routes for wear-resistant scraper flights.

Our wider capability supports custom industrial machinery metal parts and related conveyor components for mining, material handling and process equipment. The customer drawing determines the required material, connection features and supply condition.

Scraper conveyors can use different strand arrangements, scraper widths and connection styles. A chain link made for one machine should not be presumed compatible with another conveyor simply because the parts appear similar.

Types of Forged Chain Links, Scraper Flights and Conveyor Connections

SIMIS manufactures different metal parts within a scraper conveyor assembly. Distinguishing tension members from wear elements is important when choosing the manufacturing route.

Forged Links and Connecting Forks

Forged chain links transfer force along the conveyor. Their profiles may include clevis ends, eyes and connecting sections, but the final geometry must match the joint arrangement and drive sprocket. SIMIS manufactures compatible forged parts to the approved pitch and connection drawing.

Scraper Flights and Wear Parts

Scraper flights carry or push the conveyed material. Flat or shaped flights may be fabricated from abrasion-resistant plate, while suitable complex parts or replaceable wear elements may be cast. These components are not necessarily made from the same alloy as the tensile chain links.

Pins, Bushings and Sprocket Blanks

Joint pins and bushings connect articulated sections. Sprocket blanks are separate drive components whose finished tooth geometry must match the chain. SIMIS supplies specified metal components without assuming an entire assembled conveyor drive is included.

Closed-Die Forging, Casting and Wear Plate Processes

Closed-die forging is the main manufacturing emphasis for suitable heavy-duty scraper chain links. Other processes are used where the part geometry and material justify them. Forging, casting and sheet metal fabrication should not be described as interchangeable methods for every chain component.

Closed-Die Forging of Alloy Steel Links

During closed-die forging, a steel blank is heated and pressed into an impression die to form the link or fork profile. The process is useful for suitable components with integrated arms, eyes and solid connecting sections. Final material properties and any subsequent processing are determined by the specified grade and order conditions.

SIMIS provides closed-die forging and steel forging services for appropriate OEM steel parts. Forging does not automatically eliminate all discontinuities or guarantee a particular chain breaking load or fatigue life.

Sand Casting and Cast Wear Components

Sand casting forms a casting by pouring molten metal into a prepared sand mold. For scraper equipment, it can be suitable for approved steel scraper bodies, sprocket blanks and mounting structures. Replaceable wear components may use special cast alloys where the operating abrasion and impact conditions permit.

SIMIS offers sand casting and steel casting services. Highly abrasive applications may call for cast wear parts, but high-chromium white iron is not a general substitute for ductile forged chain links.

Shell Mold and Investment Casting for Smaller Fittings

Shell mold casting provides an option for repeat-production metal fittings with compatible geometries. Investment casting can produce selected intricate smaller steel parts. SIMIS offers shell mold casting and investment casting where appropriate for the specified component.

Fabrication of Wear-Resistant Steel Flights

Many scraper blades are made from steel plate rather than cast metal. Suitable abrasion-resistant plate can be cut, formed and joined to produce the specified width, height and attachment profile. SIMIS offers metal plate fabrication for compatible products. AR400 and AR500 are plate product designations, not cast iron grades.

Alloy Steel, Abrasion-Resistant Castings and Plate Materials

Material selection depends on the part function: forged alloy steels for suitable tensile members, approved cast alloys for wear-contact parts, steel plate for fabricated flights, and stainless steels for certain corrosion-exposed environments. Final suitability is defined by the customer specification.

Forged Alloy Steels for Links and Connectors

40Cr, 42CrMo and AISI 4140 are relevant steel families for selected forged conveyor components. Exact chemical compositions and supply standards must be confirmed rather than treating nominally similar national grades as identical. 20CrMnTi may be appropriate for certain pin or joint parts under the specified condition.

Cast Wear Alloys Versus Abrasion-Resistant Plate

High-chromium white iron and manganese steel are casting material families; AR400 and AR500 refer to abrasion-resistant steel plate products. Their wear behavior differs, especially when abrasive service is combined with impact. SIMIS supplies the alloy and manufacturing form specified by the OEM and does not recommend substituting these materials without approval.

Stainless Steel for Special Environments

304 and 316 stainless steels may be specified for compatible conveyor attachments exposed to moisture or corrosive service. Wrought and cast stainless steels use different material designations. Corrosion resistance alone does not establish the required chain tension capability or wear life.

Applications of Custom Scraper Conveyor Components

Scraper conveyor chains are used to transport bulk material through machinery-specific troughs. The same general principle serves several industries, but material selection depends on abrasion, temperature, chemistry and the approved equipment configuration.

Coal Mining and Mineral Processing

Coal and mineral handling uses robust chain links, pins, sprockets and scraper flights. SIMIS supplies suitable forged steel links and approved wear components for mining machinery applications.

Cement, Clinker and Ash Handling

Cement plants and ash handling systems can require scraper parts exposed to abrasive fines or elevated temperatures. Suitable forged connectors, cast wear parts and plate flights are manufactured according to the specified material and temperature conditions.

Waste Treatment and Recycling

Recycling facilities and waste processing equipment can use chain conveyors to handle residue and solids. The supplied metal components may require specified corrosion and wear resistance depending on the processed material.

Fertilizer and Bulk Material Production

Fertilizer and agricultural material handling can involve granules, powders and moisture-exposed conditions. SIMIS manufactures compatible links, flights and attachments to the drawing and stated material grade.

OEM Scraper Chain Metal Components Made to Customer Drawings

SIMIS focuses on custom metal manufacturing for industrial conveyor parts. The available scope includes forged chain links, connecting forks, pins, cast or fabricated scraper flights, sprocket blanks and specified attachments, rather than a promise to supply a complete turnkey conveying installation.

Manufacturing routes may include closed-die steel forging, selected sand or shell mold casting, investment casting for compatible fittings and wear plate fabrication. Components can be supplied as blanks or finished parts according to the approved order.

For related suspended handling systems, SIMIS also supplies custom overhead conveyor chain components, which have a different chain and trolley construction.

Machining, heat treatment, coatings and inspection are performed when required in the purchase specification. Working load, compatibility, safety and the performance of the final conveyor system must be established under the relevant OEM requirements.
