Plastic fasteners are ubiquity

Introduction to plastic fasteners

Plastic fasteners for the beginning of the installation of fastening fasteners used in connection, a wide range of uses, in the car constitute the four plates are large-scale use. The main types are divided into body fasteners, interior fasteners, chassis and engine fasteners and electrical fasteners, including body fasteners mainly for all types of nuts and blocking pieces, interior fasteners mainly for all types Standard plastic parts, chassis engine to all types of pipe clamp-based, electrical part of the wiring harness fastening belt and line guard-based.

Plastic fasteners a wide range of different forms, the role of the principle of roughly the same, that is, through the role of fasteners, the two separate parts of the original fixed connection. as the picture shows:


At present, commonly used materials to nylon 6, nylon 66, POM-based, mainly to consider the physical properties of the first indicators of high and low temperature performance, the second is the impact of performance, the third is the ability to stretch, because the need to consider Product life and ease of installation, and help reduce body weight.

The product is suitable for chassis, engine and interior

Plastic fasteners are ubiquity

1. Plastic sleeve

Suitable for assembly of silent hinges; for assembly tolerances DIN h6-H7; assembled bearing clearance is 1% of shaft diameter; resistant to dirt, climate and most chemicals.

2. Plastic gears

Plastic gears are made of wear-resistant, self-lubricating polyoxymethylene (POM) plastic for injection molding without the need for additional lubricants after installation. They can be used in environments up to 95 ° C.

3. Plastic strain relief clip

Plastic stress relief clip is also called plastic power cable buckle, can greatly save the relevant production costs, eliminating some additional installation costs and steps, installation, two power cord buckle through the attached hinge or plastic cable easily folded closed , So that the cable clasp, the installation of the power cord buckle must be perpendicular to the surface to be installed, and then use a common force clamp clamped power cord buckle above the specially designed groove will be placed smoothly into the installation location card position Available in a bullet-shaped, streamlined head design, the product is free from the traditional complex and cumbersome tape guards in a limited space. The product is securely fastened and holds wires and cables to protect them from being pulled And reverse the irregular sharp edges from the edge of the damage panel, the product in line with UL strict fire-retardant certification, black thermal stability of nylon injection molding, the maximum temperature of 105 degrees Celsius.

4. Plastic damper

Plastic dampers can be used to control the movement of flap, distribution box doors and appliance doors, etc., is a silent mobile silicon dampener improved products, simple installation time-saving, there are 8 kinds of torque to choose from, with self-lubricating material No additional oil, maintenance-free.

5. Plastic grease cap


Plastic grease cap in accordance with DIN71412 and NEN2435 standards, providing yellow and red two colors, anti-fouling, and lubrication points can be marked.

Plastic products category (by using the characteristics of classification)

by using the characteristics of classification

Plastic Product Categories
    According to name different types of plastics used feature, usually plastic into common plastics, engineering plastics and specialty plastics three types.

     GE Plastics

    Generally refers to the production of large, versatile, forming a good, cheap plastic. GE Plastics has five varieties, namely polyethylene, polypropylene, polyvinyl chloride, polystyrene and ABS. They are thermoplastics.

     plastic

    Generally it refers to can withstand external force, has good mechanical properties and resistance to high and low temperature properties, good dimensional stability, can be used as plastics engineering structures, such as polyamide, polysulfone and the like.

    In turn divided into general-purpose engineering plastics engineering plastics and special engineering plastics into two categories.

    General engineering plastics include: polyamides, polyoxymethylene, polycarbonate, modified polyphenylene ether, thermoplastic polyester, ultra high molecular weight polyethylene, methylpentene polymer, vinyl alcohol copolymer.

    Special engineering plastics have crosslinked non-crosslinked type of points. Crosslinked include: polyamino bismaleamic, poly triazine, crosslinked polyimide, heat-resistant epoxy resin and other means. Non-crosslinked include: polysulfone, polyether sulfone, polyphenylene sulfide, polyimide, polyether ether ketone (PEEK), etc.

     special plastic:    Generally refers to a special function, it can be used for plastic aviation, aerospace and other special applications. Such as fluorine plastic and silicone has outstanding high temperature, self-lubricating and other special functions, reinforced plastics and foams with special properties of high strength, high damping, these plastics are all areas of specialty plastics.

    a strong plastic: reinforced plastic material in the shape can be divided into granular (eg Gaisu reinforced plastics), fibers (such as glass fiber or glass cloth-reinforced plastic), the sheet (such as mica reinforced plastics) three. Press material can be divided Burkina reinforced plastic (such as rags to enhance or asbestos reinforced plastics), inorganic mineral-filled plastic materials (such as quartz or mica filled plastic), fiber reinforced plastics (such as carbon fiber reinforced plastics) three.


    b Foam: Foam can be divided into rigid, semi-rigid and flexible foams three. Rigid foam no flexibility, compression great hardness, only up to a certain stress was deformed, not restitution after stress relief; soft foam full flexibility, compression hardness is small, it is easily deformed, stress relief after energy restitution, residual deformation small; hard between his soft foam semi-rigid foam between flexibility and other properties.
