PCB (Printed Circuit Board) is a thin board where the electronic components, which are in pairs and assemblies, where the sides are made of copper lining to solder the legs of the components. PCB can be more than 1 layer, which I know maximum up to 12 layer.PCB is made of fiber material or the like on the non conductive part. The thickness of copper on PCB is various, there are 35 micrometer there is also a 17-18 micrometer.

Other PCB materials are phenolic or pertinax paper, usually brown, this type of material is more popular because of its cheaper price.For PCB in use for Through hole plating, usually wearing a fiberglass, because the fungus does not like this material, and The material is stronger and not easy to bend in comparison with pertinax.PCB can be found in almost all electronic equipment, such as radio, mobile, television, and others.

There are several different types of PCBs according to their usefulness: 1 side PCB (commonly used in electronic circuit such as radio, TV, etc.) PCB double side (ie both sides of PCB used to connect components) and PCB multi side (PCB part outside or inside used as media Conductor, for example in PC circuits).

Size and PCB layout design are instrumental to whether it is possible to overmold directly over the PCB. The heat and pressures associated with the overmolding process can be a detriment to certain through-hole and surface-mount components. While the temperatures of the injected polymers do not typically cause reflow of the solder, the mechanical forces present in the injection process can cause damage to either the components or their electrical integrity to the PCB.





Depending on the PCB layout and volume, there are many material choices when developing direct overmolding solutions that may affect the final choice. Thermoplastic materials and some injectable epoxy resins are the most common. In general, small compact PCB designs with all surface-mount components are good initial candidates for direct overmolding.

Bare Conductor Manufacturer Aluminium The aluminum used to produce these cables is from first fusion, with a minimum of 99.5% aluminum ensuring with this purity a high resistance to corrosion. These cables are suitable in areas with high humidity and in places with high air pollution. These cables can be supplied greased, using a chemically stable grease and neutral against aluminum








The range of bare cables for airlines is divided, depending on their use, in: - Phase Conductors - Ground Cables


Bare Conductor






AAC Conductor






AAAC Conductor






ACSR Conductor






AACSR Conductor






ACSR / AW Conductor






TACSR Conductor






ACAR Conductor






ACSS Conductor






ACSS / TW Conductor






ACS Conductor






GSW Conductor






ACCC Conductor

These are mainly made of Aluminum, Aluminum Alloy and Aluminum-Steel cables, these are replacing hard copper line cables since the last century.


ALL ALUMINUM CONDUCTOR CABLES (AAC)






Bare Conductor Manufacturer Aluminium These cables are formed by several aluminum wires in concentric layers wired in opposite directions. (ACSR)Aluminum-Steel cables arose from the need to reinforce the aluminum cables by increasing the mechanical characteristics of the same, improving the coefficient of thermal expansion and ensuring a longer life of the driver. Since that time these drivers are the most universally employed in airlines. ACSR cables (Aluminum Conductor Steel Reinforced) are formed by wires of high purity hard temper aluminum, placed in concentric layers over a wire core or galvanized steel wire.






COMPACTED ALUMINUM WIRE REINFORCED with steel core (AWG-MCM) This cable is a classic seven-wire formed by Circular section Aluminum-Steel, in which manufacturing process is given him a sectoral shape to the wires of the outer layer. eliminating the existing gaps. Its main job is in medium and low voltage lines providing the following advantages: -Decrease in total diameter for the same effective section with consequent advantages in terms of wind action, ice sleeves, protection against humidity, etc. - Advantage to the connection, due to a larger contact surface


Aluminum coated steel (Alumoweld type) is a bimetallic product with a pure aluminum coating on a high strength steel core, metallurgically bonded. The use of this type of wire is came of the conductivity that is higher than the galvanized steel and guarantees a corrosion resistance similar to the aluminum wire, so they can be used more safely than the ACSR in zones of industrial and maritime environments.










ALL ALUMINUM ALLOY CONDUCTOR / ALMELEC (AAAC)

Almelec is an aluminum alloy (Magnesium and Silicon) used in conductors for power lines. The advantage of these cables against ACSR are:






- Cheaper infrastructure due to:






• Longer runs (less supports required) due to lower weight and high breaking load (arrow is less)


• Better reuse of waste because it is a homogeneous cable






- Easy installation






• Greater surface hardness than aluminum (less shock sensitive)


• Better tensile strength


• Less weight, better handling of reels


• Easy attachment of cable ends Almelec greased cables, both inside and outside, goes really well in installations near the sea and in areas with high pollution.

Air operated diaphragm pumps are designed for general use. They can easily pump from clean, light viscosity fluids to corrosive, abrasive medium viscosity fluids and can transfer large particles without damage. Due to their pneumatic motor, they could be used in potentially explosive areas.













These pumps offer the ability to vary the flow outlet and discharge pressure as slow as 0.26 gallons (1liter) per minute up to 275 gallons (1041 liter) per minute for our larger sizes and adjust fluid pressure up to 125 p.si. (8.6 bar), by using just an air filter / regulator and a needle valve.











































All ARO pumps are available with convoluted diaphragms offering long product life and reduced maintenance. Metallic Materials:




Aluminium




Cast Iron




Stainless Steel

SINOMOULD is a famous China Mould manufacturer, efforts for realizing the world famous China Mould manufacturing Group and China Mould technologies innovator. SINOMOULD is mean to China Mould, Mold Manufacturing, Mould Tooling or Chinese Mould. SINO MOULD CO., Ltd and SINOMOULD trade mark have been global protected. China Mould Sino Mould is a private owned China mould company which was established on 1999 year.
















The founder was included 3 persons who are Mr. Jun Lee, Miss Susan Lee and Miss Sofei Lim. At the starting of SINOMOULD, most of the China Mould factories were working for domestic market, while Sino Mould started to aim on international market. As because the purpose of mould investor buy the mould is for mass production, for this reason, there should be none stop when a large quantities of plastic molds components need to be delivered or need to be processed onto a certain assembling production line, based on the mould investors’ such demands, SINOMOULD started to investigate and study European quality standard for mould manufacturing.
