Custom Caster Wheels & Forks Manufacturer
Caster Wheels & Forks
China Simis Company specializes in engineering and manufacturing all-metal casters and brackets (wheel frames/fork frames) for global industries. These solid metal casters are primarily used in complex environments where standard elastomers such as polyurethane or rubber fail due to high temperatures, heavy loads, or corrosive chemicals.
Utilizing precision closed-die forging steel, ductile iron sand casting, and stainless steel stamping processes, our caster assemblies can withstand enormous dynamic loads (up to 10 tons per wheel) and endure high-temperature baking environments exceeding 400°C (750°F). From automotive assembly line traction conveyor systems to food-grade high-temperature baking trolleys, Simis consistently delivers the caster performance you need.
What Manufacturing Processes Are Used for All-Metal Caster Wheels and Forks?
Simis adopts four core manufacturing processes for all-metal casters and related components, including hot drop forging, sand & shell casting, heavy-gauge pressing and precision CNC turning. Each process is selected based on load demand, component type and working environment to ensure high strength, wear resistance and smooth rolling performance.
| Process | Best For | Component Suitability | Key Engineering Advantage |
| Closed-Die Forging | Heavy-duty forks, kingpinless swivel mounts, solid steel wheels. | Carbon Steel (1045), Alloy Steel (4140). | Indestructible Strength. Aligns the grain structure of the steel, preventing catastrophic failure or bending under massive shock loads. |
| Sand Casting & Shell Mold Casting | Standard heavy-duty wheels, thick-walled yokes. | Ductile Iron, Gray Cast Iron. | High Load & Wear. Ductile iron provides excellent tensile strength and shock absorption, while gray iron offers a cost-effective, high-temperature rolling surface. |
| Sheet Metal Fabrication | Medium-to-heavy duty top plates and fork legs. | Stainless Steel (304/316), Zinc-Plated Steel. | Corrosion & Cleanability. Thick metal stamping provides a highly rigid structure with a smooth surface ideal for washdown environments. |
| Precision CNC Turning | Wheel treads, V-grooves, bearing bores. | Forged Steel, Cast Iron, Aluminum. | Perfect Concentricity. Ensures the wheel rolls perfectly smooth on tracks or floors, reducing rolling resistance and bearing wear. |
How to Select Materials for All-Metal Caster Wheels and Forks?
Material selection for all-metal casters depends on load capacity, temperature, corrosion resistance and safety requirements. Simis supplies forged steel, ductile/cast iron, stainless steel and solid aluminum to suit heavy load, high temperature, sanitary and explosive-proof working scenarios.
| Material Category | International Grades | Key Attributes | Typical Industrial Application |
| Forged Steel | AISI 1045 / 4140 | Ultimate load capacity and impact resistance; will not chip or break under extreme shock. | Aerospace towlines, heavy machinery moving, die-handling carts. |
| Ductile Iron / Cast Iron | ASTM A536 | Exceptionally easy to roll; withstands continuous high temperatures without deforming. | High-temp paint curing ovens, foundry carts, scrap metal bins. |
| Stainless Steel | AISI 304 / 316 | 100% rust-proof and highly resistant to harsh cleaning chemicals; non-magnetic options available. | Pharmaceutical clean-rooms, food processing, maritime equipment. |
| Aluminum Alloy | A356 / 6061 | Lightweight, non-sparking, and resistant to many chemicals and moisture. | Manufacturing environments, lightweight trolleys. |
What Precision Machining & Secondary Operations Are Provided?
Simis offers full-range precision machining and post-processing services for all-metal casters, including tread profiling, bearing bore machining, surface protection and high-temperature lubrication, to guarantee flexible movement, long service life and adaptability to harsh working conditions.
·Tread Profiling:
CNC turning of the wheel surface. Options include Flat Face (for concrete floors), Crowned Face (for easier turning), and V-Groove / U-Groove (for running on inverted angle iron or pipe tracks).
·Bearing Bore Machining:
Precision honing of the wheel hub to accept high-temperature roller bearings, precision ball bearings, or maintenance-free bronze bushings.
·Surface Protection (Forks):
Thick Zinc Plating or Yellow Dichromate for carbon steel forks to prevent rust, or Electropolishing for stainless steel forks to eliminate bacterial harborage.
·High-Temp Lubrication:
Pre-packing swivel raceways and wheel bearings with specialized high-temperature grease rated for continuous oven use.
What Are the Industry Applications for All-Metal Casters?
All-metal casters are widely applied in automotive, aerospace, industrial baking, coating, foundry, food and pharmaceutical industries. We match dedicated materials and structures according to load, temperature and sanitary standards to meet different operational demands.
| Industry Sector | Typical Cart / Application | Required Metal Component |
| Automotive | Heavy assembly line tow-trains. | Forged Steel Kingpinless Casters for continuous high-speed towing. |
| Industrial Baking & Coating | Powder coating racks, bakery ovens. | Cast Iron Wheels with High-Temp Bearings to survive continuous heat cycles. |
| Architecture and Engineering, Mining | Scrap carts, material transport. | V-Groove Forged Steel Casters running on guided heavy rail tracks. |
| Food & Pharmaceuticals | Meat processing vats, chemical washdown carts. | 100% 316 Stainless Steel Forks and Wheels with sealed raceways. |
| Logistics, Warehousing, and Handling | Traction wheels for transfer carts, electric pallet trucks, and AGVs (Automated Guided Vehicles) supporting heavy-duty vertical racking systems. | Select casters made of cast iron, aluminum alloy, or forged steel based on specific scenarios and requirements. |
How Are All-Metal Casters Classified by Structural Design?
Based on structural features and usage functions, all-metal casters are divided into five main types, covering heavy-duty anti-shear, medium load, straight-line movement, track running and super load-bearing models to adapt to diverse industrial moving demands.
·Kingpinless Swivel Forks:
The ultimate heavy-duty design. By eliminating the traditional kingpin (which is prone to shearing), the top plate and inner raceway are forged as a single piece, distributing shear forces across a massive ball bearing ring.
·Standard Kingpin Swivel Forks:
Ideal for medium-to-heavy loads, utilizing a heavy forged bolt and nut to hold the raceways together.
·Rigid (Fixed) Forks:
Heavy-duty welded steel or cast yokes used for straight-line travel and tracking accuracy.
·V-Groove Metal Wheels:
Specially machined wheels designed to operate on inverted angle-iron tracks, creating an automated-style production line without the cost of a conveyor system.
·Dual-Wheel (Twin) Casters:
Spreads extreme tonnage across two metal wheels to protect the factory floor and reduce the effort required to initiate a turn.
What Are the Simis Custom Engineering & OEM Advantages?
With in-house forging and casting capabilities, Simis provides professional custom engineering and OEM solutions for metal casters. We optimize load structure, floor contact pressure and swivel offset to achieve super load capacity, floor protection and stable towing performance.
·Extreme Tonnage DfM:
Because we forge and cast in-house, we can custom-engineer wheel wall thicknesses and fork leg widths to meet specific dynamic tow-load requirements, achieving capacities exceeding 10,000 kg per caster.
·Floor Protection Engineering:
We calculate the exact contact pressure of our metal wheels to ensure they do not damage your specific concrete or steel floor under max load.
·Custom Swivel Leads:
We optimize the "swivel offset" (the distance from the center of the swivel to the center of the wheel) to balance easy turning against trailer-sway during high-speed towing.
What Quality Control & Performance Validation Are Implemented?
Simis conducts strict multi-dimensional tests on all-metal casters, including dynamic tow test, impact & drop test, high-temperature cycling and salt spray test, to verify service life, structural stability, high-temperature resistance and corrosion resistance.
·Dynamic Tow Testing:
Casters are subjected to continuous loaded runs on drum testers to evaluate bearing life and swivel fatigue under high-speed conditions.
·Impact & Drop Testing:
Simulating a heavily loaded cart dropping off a ledge to ensure the forged steel forks do not bend and the cast iron wheels do not shatter.
·High-Temperature Cycling:
Exposing the casters to 300°C+ environments for extended periods to ensure bearings do not seize and grease does not liquefy.
·Salt Spray Testing:
Validating the corrosion resistance of our zinc-plated and stainless steel rigs over 500+ hours.
