Product Name: Yongjing Blind Hole Injection Molding Knurled Nut
Technical Standard: GB809
Product Grade: Grade A
Material: Brass
Surface Treatment: Natural Color
Product Type: Blind Hole Knurled Nut
Product Description
Product Overview
This product is a blind hole injection molding knurled nut complying with GB809 standard, manufactured from high-quality brass material. The nut features a blind hole design (one end closed) with knurled texture on the outer circumference, optimized specifically for the plastic part injection insert process. During the injection molding process, it is pre-embedded in the mold through precise positioning, and the molten plastic fills the knurling grooves and the bottom of the blind hole. After cooling, a firm mechanical interlock is formed, providing high-strength and high-reliability built-in metal thread connection points for plastic components.
Core Advantages
-
Firm Combination with Injection Inserts: The knurled design and blind hole structure ensure all-round mechanical interlock with plastic, featuring excellent tensile and torsion resistance.
-
Leakage Prevention and Attractive Appearance: The closed bottom of the blind hole can prevent plastic from seeping into the thread hole during injection molding, protecting thread cleanliness and ensuring a neat appearance.
-
Precise Positioning and Convenient Installation: The knurling facilitates positioning and fixing in the mold, simplifying the injection production process and improving production efficiency.
-
Corrosion Resistance and Conductivity: Brass material provides good corrosion resistance, thermal conductivity and electrical conductivity, extending service life.
Applicable Industries
-
Plastic Component Manufacturing: Plastic parts that require built-in high-strength thread connections, such as automotive plastic interior parts, home appliance casings, and tool handles.
-
Electronic and Electrical Industry: Inserts that require conductivity or grounding, such as terminal bases, electrical switch casings, and sensor plastic housings.
-
Medical Devices and Equipment: Plastic components with high hygiene requirements, such as medical device casings, handheld instrument handles, and disposable consumables.
-
Furniture and Sanitary Products: Metal thread pre-embedding for products such as plastic furniture connectors, faucet valve core bases, and shower head casings.
-
Industrial Equipment and Instruments: Industrial products such as instrument casings, filter housings, and plastic connectors for pneumatic components.
-
Consumer Electronic Products: Communication device casings, wearable device housings, plastic frames for audio-visual equipment, etc.
-
Toy and Model Manufacturing: Structural parts such as model components and toy wheel bushings that need to withstand repeated assembly and disassembly.
Warm Tips
-
Please precisely design the positioning dimensions of the insert in the mold according to the shrinkage rate of the plastic material (such as ABS, PP, PC, nylon, etc.).
-
Ensure the nut is clean and free of oil before injection molding to ensure the best bonding strength with plastic.
-
It is recommended to optimize the holding pressure and time in the injection molding process to allow the plastic to fully fill the knurling grooves and achieve the best fitting effect.
