Applications

Applications of Sandwich Casters

Sandwich casters are highly versatile and designed for a variety of industrial and commercial applications. Their durable multi-layer construction, combined with noise and shock-reducing features, makes them a reliable choice across multiple sectors.

Manufacturing & Warehousing

In manufacturing plants and warehouses, sandwich casters are essential for moving heavy-duty equipment and carts. Their robust design allows them to carry substantial loads while maintaining smooth mobility. The shock-absorbent TPR layer reduces wear and tear on both the casters and the floors, ensuring long-term performance in high-demand environments.

Logistics & Distribution

For logistics and distribution centers, sandwich casters excel in providing quiet and stable transport of goods. They are perfect for handling heavy loads, with the added benefit of noise reduction, which is particularly useful in fast-paced environments. Their ability to absorb shocks ensures that goods are moved safely and efficiently, even across uneven surfaces.

Medical Equipment

In medical settings, where quiet, smooth movement is vital, sandwich casters provide the stability and noise reduction necessary for medical carts, beds, and other equipment. The soft TPR layer allows for silent operation, reducing disruptions in hospitals and clinics while ensuring reliable, hygienic transport of sensitive items.

Exhibition and Event Equipment

For exhibitions and event setups, sandwich casters offer both mobility and aesthetic appeal. These casters ensure smooth movement for portable displays, booths, and event equipment. With customizable color options, they can be tailored to blend seamlessly with the overall design, maintaining a professional and polished look.

Caster Materials

Common Materials for Industrial Casters

Techin’s sandwich casters are built using high-performance materials that provide specific advantages, ensuring optimal performance in various industrial applications. Selecting the right material for your casters is crucial to meeting the demands of your environment, whether it's durability, load capacity, or noise reduction.

Material Advantages Applications
Polypropylene (PP) Lightweight, impact-resistant, and highly durable, making it ideal for harsh environments. It withstands heavy loads while maintaining structural integrity, providing longevity in demanding conditions. Used in industrial carts, machinery, and heavy equipment where high strength and low weight are essential.
Thermoplastic Rubber (TPR) Flexible and soft, offering excellent shock absorption and noise reduction. TPR also prevents floor damage and is ideal for environments requiring quiet operation. Common in warehousing, logistics, and medical equipment, where gentle, quiet movement is needed.
Nylon Extremely tough, with outstanding wear resistance and the ability to handle very high load capacities. Nylon casters are highly resilient in high-impact, heavy-duty settings. Ideal for manufacturing, aerospace, and logistics, where maximum durability and load-bearing capacity are key.
Casters Standars

European Standards for Industrial Casters

In the caster industry, several European standards serve as guidelines to ensure the quality, safety, and environmental compatibility of products. Here, we provide an overview of some pivotal standards that are commonly adhered to:

Standard Description Function Tested Qualification Criteria Testing Machine
EN840 Applies to mobile waste containers with capacities up to 1700 liters used by the general public. Specifies essential dimensions for interoperability with lifting devices. Interoperability and dimensional accuracy Containers must fit standardized lifting devices and maintain structural integrity under load Dimensional measurement devices and load testing machines
PAHs (Polycyclic Aromatic Hydrocarbons) Governs the restriction of PAHs in consumer products, including casters and wheels. Chemical content analysis PAH concentration must be below specified limits (e.g., <1 mg/kg) Gas chromatography-mass spectrometry (GC-MS)
REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) Addresses the production and use of chemical substances and their potential impacts on human health and the environment. Chemical composition and safety assessment Compliance with REACH Annex XVII and authorization list requirements High-performance liquid chromatography (HPLC), safety data sheet (SDS) review
RoHS (Restriction of Hazardous Substances) Restricts the use of specific hazardous materials found in electrical and electronic products. Presence of hazardous substances (e.g., lead, mercury, cadmium) Concentration of restricted substances must be below 0.1% (1000 ppm) except cadmium, which must be below 0.01% (100 ppm) X-ray fluorescence (XRF) spectroscopy, inductively coupled plasma mass spectrometry (ICP-MS)
EN 12530 Outlines requirements and dimensions for equipment casters and manually operated wheels used in public facilities. Dimensional accuracy, load-bearing capacity, and durability Casters must meet specified dimensions, support specified loads without failure, and pass durability tests (e.g., rolling resistance, swivel resistance) Universal testing machines (UTM), endurance testing rigs, dimensional measurement devices

These standards are integral in guiding manufacturers to produce products that are not only of high quality but also safe and environmentally responsible. Adherence to these standards is often seen as a mark of reliability and trustworthiness in the industry.

Selecting Casters

Guiding Principles for Selecting Casters

Selecting the right caster and installing it correctly is a vital aspect in ensuring the longevity and functionality of your equipment.

Consideration Description
Purpose Determine the specific function the caster will serve, such as mobility, stability, or braking.
Load Capacity Ensure the caster can support the weight of the furniture and any additional loads.
Floor Compatibility Choose a caster wheel material that won't damage the flooring.
Mounting Method Select the appropriate mounting option for your furniture.
Durability Consider the materials and construction quality for long-lasting performance.

Selecting the right caster and installing it correctly is a vital aspect in ensuring the longevity and functionality of your equipment.
We also outline a systematic approach to guide you through the process of selecting and installing casters:

  • Determine Your Product and Mounting Type: The first step involves identifying the type of product you are working with and the appropriate mounting method. Different products may require varied mounting techniques, and understanding this is crucial in selecting the right caster.
  • Understanding Load Capacity: Before selecting a caster, it is essential to determine the load capacity it needs to handle. The load capacity is calculated using a specific formula that considers various factors including the deadweight of the transport unit, the maximum additional load, and the number of wheels or casters used. Safety factors, influenced by the speed and the ratio between wheel diameter and height of the obstacles, also play a significant role in determining the load capacity.
  • Select Your Tread Material: The tread material significantly influences the operational comfort, smooth-rolling performance, and resistance characteristics of the wheels or casters. It is vital to choose a tread material that is softer than the floor to prevent damage.
  • Determine Maneuverability: Understanding the maneuverability factors such as starting, rolling, and swivel resistance is crucial in selecting the right caster. These factors are influenced by various elements including wheel diameter, load, floor condition, and bearing type.
  • Select the Bearing Type: The bearing type is a critical aspect that affects the rolling characteristics of a wheel. Different bearing types, such as plain bore bearing, roller bearing, and central ball bearing, offer varied performance characteristics and are suitable for different applications.
  • Consider Your Application’s Environmental Influence: The environmental conditions where the caster will be used should be considered, especially in cases where the components may come into contact with aggressive substances. Factors such as chemical resistance, temperature, and humidity can influence the choice of caster.
  • Additional Options and Requirements: Depending on your specific needs, you might require additional features such as locking systems for rolling and/or swivel motions, or brake systems. Understanding these additional requirements is vital in selecting the right caster.
