As a common fixture in daily and industrial environments, the effectiveness and safety of packing belts are of paramount importance. This paper will systematically explain the correct use of band strapping tool,from four aspects: tool selection, operation steps, notice and latermaintenance.
How to correctly choose the appropriate type and specifications of strapping tools?
Determine requirements based on usage scenario.
The tape must be selected in strict accordance with specific conditions to avoid failure due to environmental or load mismatch.
Environmental Adaptability
Outdoor applications: Choose nylon cable joints with UV inhibitors to prevent material from aging and cracking due to prolonged exposure to sunlight.
· Humid environments: In bathrooms and basements, use wet-resistant cable ties (such as polyester fiber cable ties) or stainless steel steel cable ties to prevent common nylon cable joints from failing due to water absorption and expansion.
· Corrosive environments: In chemical and shipbuilding environments, stainless steel steel cable ties or specially coated cable ties (e.g. galvanized or epoxy coated) are used to prevent acid and alkali corrosion.
Load Capacity and Size
The tensile strength is selected according to the weight of the bound object. For example, it is recommended that nylon cable joints with a nominal load of 50 kg not exceed 40 kg (70%-80% of the nominal value) to avoid the risk of breakage.
· Diameter Adaptability: For objects more than 5 cm in diameter, heavy-duty cable connections with a width of at least 10 mm shall be used. For precision electronic circuits or small parts, narrow ties with a width of 4-6mm should be used to minimize space usage.
Special needs
· Temporary Fixtures: Removable cable ties such as Velcro Velcro plastic buckles) can be used for exhibition setup and temporary tying purposes to facilitate reuse.
· Industrial High-Strength Requirements: Cable joints of reinforced nylon or stainless steel with a tensile strength exceeding 200 kg are recommended to be suitable for fixing heavy equipment.
Matching materials to performance
Cable ties act differently depending on the materials they are made of, therefore pick the right cable bridge for your needs:
- Nylon cable ties are light and can stand up to the weather. They get soft easily when it's hot (melting point is about 220 degrees Celsius) and hard when it's cold, therefore they're great for indoor use.
- Stainless steel cable ties won't rust or melt (the melting point is 1400°C). They can be utilized in hard environments like chemistry labs and oceans, but they cost more.
- Polyester cable ties are very strong and can stand up to UV light. They are not as heat-resistant as nylon, but they are often used in farming (such wrapping vines) or outdoor baling.
Brand and Standard Certification
Priority is given to well-known brands with international certification,such as 3M and Hellermann Tyton,such as UL62275, to ensure their tensile strength and flame-retardant properties meet standards. Poor cable ties may have loose buckles or brittle material, increasing safety risks.
Basic operating steps and precautions when using strapping tools
Correct operation ensures that cable tie are secure and do not damage objects:
Insertion and Securing: Turn the serrated side of the cable tie toward the object to be tied (to avoid scratching the surface), wrap the cable tie around the object, and insert the tip into the buckle hole. Pre-tighten manually until it fits comfortably.
Tightening and locking: Tighten the end of the cable tie at a steady speed until the required tightness is achieved. Once the clasp joins the jagged side, stop applying force. Avoid too tight, so as not to cause cable tie deformation or breakage.
Excessive cutting: Use scissors or oblique tongs to cut off the end of the cable fastening clasp, leaving 2-3mm ends to prevent loosening and sharp edges to avoid scratching your hands.
For complex situations, the following methods can be used:
Temporarily Securing: Use toothpick to fasten ratchet to ratchet before tightening to prevent locking, to adjust position or tension. Once adjusted, remove toothpick to lock cable tie.
Connect multiple cable ties in parallel: When connecting thicker objects,such as tree trunks and pipes, connecting multiple cable ties in parallel disperses pressure and increases load capacity.
Cross Binding: For easily sliding objects (such as cylindrical tubes), cross binding is used to form an "X" -shaped fixed structure for stability.
Avoid the following risks during operation:
Tension control: The maximum tensile strength of nylon cable joints shall be 70%-80% of the nominal value. Avoid sudden forces that can cause an object,such as an electronic element or plastic casings, to break or damage.
Reuse Tips: For nonpermanent installation, keep the belt buckle intact. When removing, simply cut off the tail end and retain the main body of the cable tie for backup (making sure the clasp doesn't wear out).
Aviation Safety Regulations: Special industries, such as aviation and aerospace, must comply with relevant safety standards (e.g., NASA-STD-8739.4) to prevent accidents caused by loose buckles or material aging.
Maintenance and care of strapping tools after use
Wash and store:
Cable bridges can last longer if stored correctly:
- Clean after use: Clean cable ties quickly of any dirt, dust, or grease to prevent fasteners from getting stuck or joints from working properly (e.g., nylon ties that skid easily when oiled).
- To prevent dampness and rust, stainless steel steel cable ties should be washed. To prevent nylon cable joints from cracking, store nylon cable joints in dry, ventilated areas with little sunlight (humidity should be kept below 60%).
Periodic inspection and replacement:
After extending use, check the following questions:
- Wear inspection: Check cable ties for cracks, deformation or loosening. Replace damaged parts in a timely manner (for example, steel buckle require to be completely replaced).
- Rust-resistant oil (e.g. WD-40) is applied to metal parts steel buckle) to reduce friction and extend service life.
Management equipment, such as baling machines:
If you're using a binder, here are a few things you should always look out for:
- Clean feed tracks: To prevent tape from sticking and machine damage, you should regularly remove debris from feed tracks and blow dust away with compressed air.
- Temperature control: The strapping machine's soldering iron temperature should be controlled to around 300°C to avoid excessive temperatures that may cause the tape to break or may cause the tape to adhere (e.g. higher temperatures required for PET tape).
- Fixer tightening: Check the screws and nuts of the binder are loose. If the crankshaft runs out of oil, use drip oil (such as sewing machine oil) to reduce wear and tear.
Conclusion:
Scenario requirements, material properties, and operating specifications must be considered in the selection and use of strapping tools. Maintenance ensures the long-term stability of the tool. Through scientific selection, standard operation and regular maintenance, the efficiency and safety of the baling machine can be improved to the maximum extent, and all kinds of safety schemes can be guaranteed reliably.
