Pre-embedded copper nuts
 Copper nuts, also known as embedded nuts and embedded copper nuts or plastic embedded nuts, are divided into hot-melt copper nuts, hot-pressed copper nuts, embedded copper nuts, and ultrasonic copper nuts according to different methods of use.Copper nuts are widely used in mobile phone housing/pen type housing/injection parts/inlaid parts for plastic parts, used as an internal thread. Generally cylindrical embossed to prevent slipping. Our factory specializes in producing all kinds of copper nuts. Similar products Quality is not inferior to imported products. It is widely used in various injection molding industries. The left figure is a standard copper nut that is the most commonly used standard. It is a GB809-88 standard embedded round nut that was issued in China in 1988. It also has a through hole and a blind hole. The specific specifications and standards are detailed in GB809- 88 embedded round nut Conventional production range: M1.2~M20 The left figure shows the blind hole type embedded copper nut. The left picture shows a hot-pressed knurled brass nut.Double knife holder embossed, brass material. Double twill knurled brass nut standard and its main types and several typical types in the industry: IUTB hot flower copper nut IUB IUC type knurled copper nut IBB IBC copper nut ITB ITC copper nut SKTB SKTC copper nut Inlaid copper nut (left). Material: C3604 lead-free environmentally friendly copper, surface pressure eight flowers. Widely used in external plastic cases such as TVs or computers. Lead-free environmental protection copper production, lead content below 50PPM, product material in line with the EU ROHS standards. Our company has strict requirements on the thread qualification rate of this product. We know that even if there is a toothless nut, it will lead to the user's entire plastic parts scrapped. The copper embedding nut in the left figure has a flange with a large outer circle. After the plastic part is embedded in the flange, the plastic part is exposed on the flange side or is even with the plastic part. The left figure is M5*9 (maximum outer diameter)*12 (total height). |

Fitted round nut GB809
 Inserted round nuts, also known as embedded copper nuts, are one of the fastener standards issued by China in 1988. The standard number is GB/T809-88.It is divided into two types of through holes and blind holes, and the surface adopts a straight grain and middle groove scheme. Due to the looseness of the size of the national standard, On the basis of this, we have increased the accuracy requirements, especially the tolerance of the internal thread diameter to avoid leakage during the injection molding process. This type of copper insert round nut or other material (such as iron or stainless steel) injection insert round nut, although the style is simple, but as the injection molding is still the first choice for inserts. The figure on the left shows the insert round nut for injection molding of copper material. It can be seen from the figure that the clear edges and corners of the grain are clearly visible on the market, which is unmatched by ordinary products on the market. The specification on the left is M3*6. In addition to the brass brass as the material of the GB809-88 standard embedded copper nut In addition, our company also produces: Stainless steel embedded round nut Carbon steel embedded round nut There are two types of embedded round nuts: through holes and blind holes Note: The product on the right is a blind hole type embedded copper nut. We call it type B, (through-hole mounting nuts are type A). Users pay attention to distinguish between design and purchase Specifications on the left: M8*12*14 and M6*10*16 Material: C3604 Brass |

Hot melt nut IUTB
 Hot-melt copper nut IUTB type (as shown on the left). Materials are generally used: C3604 fast cutting brass, C3604 lead-free brass.It is pressed into the plastic preset hole with heating and forms a firm internal thread after cooling. Available thermal or ultrasonic type, load quickly plasticity plastic material, positive and negative phase spiral pattern can provide high torque and high tension. Features: Allows less fleshy, straight hole design Hot melt or ultrasonic method can be used to quickly install Round head guide design, good positioning effect; not easy to skew Staged outer diameter design, gradually into the plastic, the parent material plastic is not easy to crack Double oblique design in the opposite direction, tightly integrated with plastic to increase torque pull Left is M3X4.55X5 Our hot-melt nut embossing is visible The hot-melt hot-pressed nut embedment technology uses the head of the welding head and the appropriate pressure. Instantly squeeze the nut into the hole reserved for plastic, fixed at a certain depth, after completion, no matter whether the pulling force or torque is comparable to the strength in the traditional mold, Eliminates the disadvantage of damage to the injection mold and slow ejection |
Stainless steel embedded nuts
 Stainless steel plastic implantable round nut, see GB809 stainless steel embedded nutMaterial: SUS303 or SUS316F Standard: GB809-88 Available for production: M3~M12 The left picture shows the national standard GB809-88 stainless steel embedded round nut,Specifications: M4*6*5 Application: Injection moulded plastic parts or plastic parts to form internal threads Although most of the plastic implant inserts use copper material as the first choice, there are still some application environments that use stainless steel as a solution for plastic implants, such as: 1, anti-rust work place, stainless steel SUS303 or 316F has better rust resistance than brass 2, higher hardness and wear resistance, stainless steel SUS303, 316F has higher hardness and wear resistance than brass The left picture shows a stainless steel knurled plastic nut embedded with a rhombus Material SUS303 Specifications: M5*8*8 IUTC stainless steel hot pressed nut, stainless steel double twill embossed nut, Left specification: M3*5*5 Left figure material: SUS303 Process: The use of left oblique and right oblique embossing wheels for automatic lathe turning Application: Through heating after melting into the plastic reserved hole or pressing directly into the reserved hole of the plastic part, the plastic part can also be implanted through the mold injection method. For specific IUTC related dimensional standards, please refer to the production and use parameters of the IUTB hot-pressed copper nut of copper material. In addition to the different materials, the dimensions and the requirements for plastic parts are completely consistent. |

Ultrasonic copper nut
 Implantation of internal thread inserts of plastic parts by means of ultrasound, we classify them as ultrasonic nuts, In fact, the so-called ultrasonic nuts are not much different from the hot-melt nuts on our website and are even interchangeable.Ultrasonic nuts and hot-pressed nuts have some common features: Plastic parts need to have reserved holes, and the nut has a tapered shape, just like the left picture, The ultrasonic nut and the hot-melt nut have the same shape as the hot-melt nut, and the leading end of the ultrasonic nut generally has a guide portion to facilitate pressing and embedding into the plastic reserved hole. On the left, this snail has a size of M3*4.2*5. Its diamond pattern is as beautiful as a diamond. The ultrasonic nut has a variety of patterns, including a diamond pattern (as shown in the figure on the left), a ruled pattern, a chamfered pattern (as shown below), or a combination of various patterns. However, they all have some commonalities. Their embossing is symmetrical, which is obviously different from that of hot-stamped nuts with right and left twill or single twill. We know that the principle of ultrasonic implanting is the same as that of hot embedding. The difference is that hot embedment uses plastic to melt or soften by heating nuts. The ultrasonic nut uses plastic (the contact with the nut) to soften by means of high-frequency vibration. Note that it is soft and not yet melted. Obviously, it has an inherent advantage: the installation speed of the ultrasonic nut is faster because the metal nut needs to be transferred by the metal head to heat the nut before it is pressed into the plastic hole. The ultrasonic method does not require this process. |
