The overall production process of plastic products

2025-06-06

The overall production process for plastic products is as follows: raw material selection — raw material coloring and compounding — mold design — injection molding via machine — printing — assembly and final product inspection — packaging and shipment. First, determine the mold materials and select standard components. When choosing mold materials, in addition to considering product precision and quality, it’s also essential to make the right selection based on the actual machining and heat‑treatment capabilities of the mold manufacturer. Furthermore, to shorten the manufacturing cycle, make the most of existing standard components whenever possible. Dongguan Anmei Kou Co., Ltd., abbreviated as Anmei Kouju, was founded in 1996 and originally operated under the name Guangzhou Nai’an Company. To better meet customer needs,

Main Categories of Fasteners

2025-06-06

Basic fastener types can be broadly categorized into two major groups: metal fasteners and plastic fasteners. 1. Metal Fasteners: (1) By Function: Square buckles, alligator-style buckles, adjustable alligator-style buckles, round ring buckles, oval ring buckles, hook buckles (both rotating and non‑rotating), belt buckles, and other specialized fasteners. (2) By Plating Method: Similar to metal pull tabs. (3) The primary factors in determining a fastener’s specifications are its width, height, and wire diameter. For special fasteners, refer to the manufacturer’s catalog; since each manufacturer uses different molds, there may be variations in the products they produce. 2. Plastic Fasteners: (1) By Function: Alligator-style buckles, square buckles, ladder buckles, snap buckles, hook buckles, multi‑functional buckles, rope buckles, and other plastic fasteners. (2) By Material: Common materials include plastic‑steel and nylon; nylon is generally more expensive (Source: Anmei Fasteners).

Let’s take a moment to share a brief overview of the material properties of plastic fasteners, so everyone can gain a deeper understanding of these components—and perhaps find them particularly useful for bag makers. ### 1. Polyoxymethylene (POM), commonly known as “Delrin,” is a combustible material. #### Advantages: 1. Strong and highly resilient. 2. Excellent fatigue resistance. 3. Self‑lubricating with outstanding friction and wear resistance. 4. Superior heat and cold resistance. #### Applications: - Snap fasteners - Hook-and-eye closures - Double‑D rings - Round‑D rings - D‑rings - Rope‑style fasteners --- ### 2. ABS is a combustible material. #### Advantages: 1. Excellent surface appearance. 2. Outstanding electroplating performance. 3. Exceptional impact and low‑temperature toughness. 4. Minimal shrinkage during molding, ensuring high dimensional accuracy. 5. Excellent resistance to acids and alkalis. #### Applications: - Electroplated fasteners - Handle straps --- ### 3. Polyvinyl Chloride (PVC) is a self‑extinguishing material. #### Advantages: 1. Flexibility can be freely adjusted. 2. Hard yet highly resilient. 3. Excellent weather resistance. #### Applications: - Shoulder pads - Handles - Base components --- ### 4. Polyamide (PA), commonly known as “Nylon,” is a self‑extinguishing material. #### Advantages: 1. Strong and tough, with excellent impact strength. 2. Self‑lubricating, offering superior wear and abrasion resistance. 3. Outstanding heat resistance. #### Applications: - Snap fasteners - Handle components --- ### 5. Polypropylene (PP) is a combustible material. #### Advantages: 1. One of the lightest plastics available. 2. Excellent heat resistance. 3. Low water absorption, resulting in superior high‑frequency electrical insulation properties. #### Applications: - Snap fasteners - Double‑D rings - Round‑D rings - D‑rings - Handle components --- ### 6. Polycarbonate (PC) is a self‑extinguishing material. #### Advantages: 1. Exceptional impact strength. 2. Excellent heat and cold resistance. 3. Superior weather resistance. 4. Good dimensional stability. 5. Transparent and translucent properties.
