What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

Investment Casting Materials and Manufacturing Process

Mold material The performance of the molding material should not only ensure the convenient production of investment molds with accurate dimensions and high surface finish, good strength and light weight, but also create conditions for the manufacture of mold shells and good castings. Molding materials are generally formulated with waxes, natural resins and plastics (synthetic resins). All mold materials mainly prepared with wax materials are called wax-based mold materials, and their melting point is low, 60~70 ° C; all mold materials mainly prepared with natural resins are called resin-based mold materials, with a slightly higher melting point, about 70 °C. ~120℃. invest-casting.com   Precision Investment Castings China prototype company service include :  High Quality Investment Casting Parts Custom , Lost Wax Investment Casting Sand Casting , Lost Foam Casting , Gravity Casting , Die Casting , Graphite Casting , Casting Moldsmanufacturers .

알루미늄 합금 다이캐스팅의 단점을 해결하는 것이 편리합니다!

알루미늄 합금 다이캐스팅은 현재 현재의 전자제품 , 자동차 , 생활필수품 등 많은 산업과 분야에서 널리 사용되고 있습니다 . 그러나 알루미늄 합금 다이캐스팅에서 자주 발생하는 몇 가지 결함 및 해결 방법은 다음과 같습니다 .   알루미늄 합금 다이캐스팅   1. 불순물   알루미늄 합금 다이 캐스팅의 불순물 문제는 주로 특정 온도에서 알루미늄 , 규소 및 다량의 철 , 망간 , 크롬 및 기타 화합물을 포함하는 결정립과 일부 산화물로 구성됩니다 .   해결책 : 알루미늄 잉곳의 조성을 엄격하게 제어하고 , 제련로의 난로를 정기적으로 청소하고 , 정기적으로 슬래그를 처리하면 문제를 해결할 수 있습니다 .   2. 구강 문제   다공성은 다이캐스팅 부품의 내부 또는 표면에 나타나는 다양한 크기의 구멍을 말하며 , 이는 다이캐스팅 부품의 경도 부족으로 이어져 표면의 외관에 영향을 줍니다 .   Solution: 적절한 정제제를 사용하여 모공을 처리하고 , 공정을 조정하고 , 저속을 적절하게 줄이고 , 이형제가 너무 많이 분사되어 모공 문제가 해결되지 않는지 확인하십시오 .   3. 균열 문제   균열은 알루미늄 합금 다이캐스팅의 매트릭스가 파괴되고 , 외력의 작용에 따라 확장되는 경향이 있는 선형 또는 기타 라인인 기다란 틈이 형성되는 것을 의미합니다 .   솔루션 : 합금 조성을 올바르게 제어하고 , 냉각수 회로를 늘리고 , 알루미늄 합금 다이캐스팅의 구조를 변경하고 , 사출 위치를 변경하거나 증가시키면 해결할 수 있습니다 . PINJIN 서비스에는 다음이 포함됩니다 . 알루미늄 다이캐스팅 , 아연 다이캐스팅 , 마그네슘 다이캐스팅 , 투자 주조 , 모

Introduction to the reasons and solutions for the lack of sealing of car windows

  After the window glass is damaged, use glass with the same curvature as the original window glass, and check the glass guide groove and sealing strip for damage.Since car windows often fail to return to their original shape after being repaired, in addition to ensuring that the car window glass can be easily pulled or raised and lowered at this time, attention should also be paid to the sealing around the car window glass after the car window is closed.

 

When changing the roof, apply a layer of conductive sealant on the periphery of the roof. After the welding is completed, apply hemming glue all over the water trough and at the joints. This will not only help seal the body, but also It can also prevent the body from water accumulating at the weld seam due to flanging

and produce early rust. When assembling the door, paste a whole sealing isolation film on the inner panel of the door below the window. If there is no formed sealing isolation film, it can be replaced by ordinary plastic paper, and then the sealing isolation film is pasted and compacted. Production and assembly of interior trim panels.

When repairing a car door with a sealing flange, attention should be paid to repairing the damaged sealing flange and accurately restoring the shape of the original flange.After repairing the car door, check the leak tightness. The check method is: put a piece of hard paper on the sealing position, close the door, and then pull the paper to judge whether the seal is good or not according to the pulling force.If the force required to pull the paper sheet is too large, it means that the seal is too tight, which will affect the normal closing of the door, and will also cause the seal to lose its sealing performance quickly due to excessive deformation; if the force required to pull the paper sheet If it is too small, it means that the seal is not good, and the door will often block the wind but not the rain.When replacing the door, be sure to apply hemming glue on the flanging occlusion of the inner and outer panels of the new door, and block some small craft holes left during punching with the base tape.

When repairing the car circuit, the sealing rings of all the body holes and holes through the wiring harness should be installed in place, because these sealing rings not only play a sealing role, but also play a role in protecting the wiring harness.If the sealing ring is damaged or the wiring harness can rotate or move in the sealing ring, replace the sealing ring and assemble it firmly with the holes and holes of the vehicle body to stabilize the wiring harness.

When replacing the entire car body, in addition to completing the above items, a layer of sealant should be applied to the overlapped part and solder joints of the weld. The thickness of the adhesive layer should be about 1mm, and the adhesive layer must not have any virtual stickiness. , Bubbles and other defects; apply special edge-folding glue at the edge; apply 3mm-4mm elastic coating and anti-corrosion coating on the entire lower surface of the floor and the lower surface of the front wheel cover; on the upper surface of the floor and the front stand The inner surface of the board should be pasted with sound insulation, heat insulation, vibration reduction and damping film, and then covered with heat insulation felt, and then covered with carpet or decorated floor.These measures can not only greatly enhance the airtightness of the vehicle and slow down the corrosion rate of the car body, but also greatly improve the ride comfort.
