Choosing the right luggage is always not an easy job. There have been many innovations in material, design, and function over the years. Firstly, figure out if you want a softside or hardside luggage. If you\u2019ve already found your way here, that means you\u2019ve decided that a hardside luggage is your best bet.Now for the next step: material. And there are two main materials you\u2019ll find everywhere: Polycarbonate and ABS.Polycarbonate vs. ABSPolycarbonate and ABS are the most common types of plastic used in suitcases market. Polycarbonate is more flexible than ABS and has a higher impact resistance. As a result, it makes for a stronger suitcase. ABS suitcases are cheaper than Polycarbonate ones, but they are heavier and life is short.PolycarbonatePolycarbonate is an amorphous polymer (ie. plastic) with properties that make it ideal for hardside luggage. It has excellent transparency that means it is easy to make in different colors and patterns. It also has high degree of hardness and impact resistance making for durable ABS+PC luggagege. Polycarbonate is also highly temperature resistant and has some nice self-extinguishing properties.This also means it can be moulded pretty easily into different luggage shapes, making it very flexible and able to take a beating during travel.Polycarbonate is also popular to use in luggage because it's so lightweight. It can bend and dent and will easily go back to its original shape. It is almost impossible to break and has the highest level of strength of all luggage materials.ABSABS is a blend of three kinds of plastics, each with their own unique characteristics.Acrylonitrile provides chemical and fatigue resistance, hardness, and melt strength.Butadiene provides good impact resistance.Styrene provides heat resistance, processability, color and hardness.Together, ABS is great for impact resistance (ie. luggage handlers), easier processing (making into shapes) and has great mechanical properties: high heat distortion temperature, and gloss property.This makes ABS ideal for a broad field of applications, including piping and fittings, instrument and appliance housings, tool housings such as hand drills, electric screw drivers, automotive instrument panels and home appliances.In luggage, ABS is the cheapest hard material used. It's also very light and makes ABS luggage cheaper than most, but unfortunately it's also not the most durable. For most luggage makers, however, they use ABS combined with other materials to make a stronger suitcase overall.Hongtu Weiye Luggage Co., Ltd offers you a complete solution for PC\/ABS luggage equipment project.Starting from Dryer blender-Extrusion line-Vacuum forming-CNC cutting-Sewing machine-Rivet machine-sewing machine-Assembly conveying lineAnd all related accessories like wheels , trolley, screws, hand rails, zippers, aluminum sash. etc.
