Main classifications of fasteners

Buckle types can basically be divided into two main categories: metal buckles and plastic buckles: 1. Metal Buckles: (1) By function: square buckle, D-ring buckle, adjustable D-ring buckle, O-ring, oval ring, hook buckle (rotating and non-rotating), belt buckle, and other special-purpose buckles. (2) By plating method: Same as metal pull tabs. (3) The specifications of buckles are mainly determined by their width, height, and wire diameter. Special buckles need to refer to the manufacturer's catalog. Products from different manufacturers may vary due to their different molds. 2. Plastic Buckles: (1) By function: D-ring buckle, square buckle, ladder buckle, side release buckle, hook buckle, multi-functional buckle, cord lock, etc., and plastic. (2) By material: Commonly used materials are POM (plastic steel) and nylon. Nylon material is higher in price (Source: Anmei Buckles).

Knowledge of the performance aspects of commonly used raw materials for plastic fasteners

A brief introduction to the raw material properties of plastic fasteners is shared with everyone to help everyone further understand plastic fasteners and provide assistance to bag makers. I. Polyoxymethylene (POM) Commonly known as: Celcon, a combustible material Advantages: 1. Strong and elastic 2. Excellent fatigue resistance 3. Self-lubricating, excellent friction and wear resistance 4. Excellent heat resistance and cold resistance Suitable for: buckles, hooks, eyelet buckles, D-rings, rope buckles II. ABS A combustible material Advantages: 1. Excellent appearance properties 2. Excellent electroplating characteristics 3. Excellent low-temperature impact resistance 4. Small molding shrinkage, excellent dimensional accuracy 5. Excellent acid and alkali resistance Suitable for: electroplated fasteners, handles III. Polyvinyl chloride (PVC) A self-extinguishing material Advantages: 1. Softness can be freely adjusted 2. Hard and strong 3. Excellent weather resistance Suitable for: shoulder pads, handles, bases IV. Polyamide (PA) Commonly known as: nylon, a self-extinguishing material Advantages: 1. Strong and has good impact strength 2. Self-lubricating, excellent wear resistance and abrasion resistance 3. Excellent heat resistance Suitable for: buckles, handles V. Polypropylene (PP) A combustible material Advantages: 1. The lightest among plastics 2. Excellent heat resistance 3. Low water absorption, therefore has good high-frequency electrical insulation performance Suitable for: buckles, eyelet buckles, D-rings, handles VI. Polycarbonate (PC) A self-extinguishing material Advantages: 1. Excellent impact strength 2. Excellent heat resistance and cold resistance 3. Excellent weather resistance 4. Good dimensional stability 5. Has permeability

Fastener Material Characteristics and Uses

The selected materials are generally POM (polyoxymethylene, commonly known as Delrin), PA, and PC. Buckles consist of male and female buckles, with webbing sewn to both ends. The length of the webbing is chosen according to different needs and is generally used for fixing the shoulder and waist. To more effectively utilize the function of buckles, more convenient and scientific buckles have been introduced, such as replaceable invisible female buckles. This is a buckle that can be easily replaced without sewing webbing. Another type is a three-way buckle, i.e., a "Y" buckle, often used in baby stroller safety products. The female buckle can be customized with logos or designs according to customer specifications and authorization, and electroplating, screen printing, or painting can also be selected. 2. Hook The materials are generally POM, PA, and PP. Generally speaking, hooks, D-rings, press studs, O-rings, square buckles, and ladder buckles are collectively referred to as hooks. Usually, hooks and D-rings are used together. The O-ring adjusts the length of the webbing, and the ladder buckle is generally used at the end of the webbing for primary fixation. Hooks can be electroplated or screen-printed, and logos can generally be designed on the ladder buckle. 3. Rope Buckle The materials are generally PA, PP, PC, and POM. Rope buckles are available in various sizes and with single or double holes, suitable for various OO ropes, nylon ropes, and elastic ropes. Logos can be designed according to customer requirements. 4. Plastic Feet The material is generally PVC. Plastic feet are available in granular and strip shapes, used at the bottom of bags or boxes to effectively protect items from wear and tear. They are an indispensable accessory for bags and boxes and have anti-slip functions, protecting items from damage due to impact in special circumstances. 5. Shoulder Pads Materials are PVC, PU, TRP, and TPE. Shoulder pads have the functions of reducing pressure and providing positioning and anti-slip. The front of the shoulder pad is called the back.
