Rotary kilns are used to uniformly heat lime, cement, carbon, fertilizer, stone and other aggregate materials. As the kiln turns the heated material is mixed, and new material becomes exposed to the flames and hot combustion gasses. Kilns are typically heated by a large flame introduced at the exit end of the process. The hot combustion gasses are then passed along the length of the kiln in a counter-flow direction. Many plants capture the hot gasses as they escape the entry end, and use this heat to pre-heat the product before it enters the kiln.


Kiln plants with two and three station rotary kilns from KHD Humboldt Wedag are top of the line. One reason: highly efficient precalcining systems, which were developed by KHD Humboldt Wedag, revolutionizing the clinkering process.

Rotary kilns no longer have to function as calciners which mean that they can be substantially smaller in size. The advantage for customers is lower investment and operating costs. These systems quickly gained excellent reputations among our customers.

Rotary dryers are almost always used for drawing moisture out of a material. Typically, they operate at temperatures between 800º – 1400ºF. Rotary kilns, however, are concerned with causing a chemical reaction. Therefore, they need to operate at much higher temperatures, between 1000º – 3000º.

Rotary kilns are designed to withstand much higher temperatures than a rotary dryer. Typically, if you are dealing with a direct fired rotary kiln, it is refractory lined with a brick or castable lining. This lining protects the steel shell. Rotary dryers are typically not lined, and their steel is not able to withstand such high temperatures. If you are dealing with an indirect rotary kiln, the kiln is not normally lined, so the shell of the drum has to be made out of a temperature resistant alloy instead of steel.

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).

Printed Circuit Board

 At its inception in the late 80s, the rapid prototyping process was largely inaccurate and the choice of materials and technologies was limited. Back then, a prototype served as a basis for discussion but could not be used for anything "serious", i.e. in a real production environment.

Since then, accuracy has improved significantly and so has the range of applications and software solutions.

The famous Magics software by Materialise is the ideal solution for driving efficiency throughout your entire Rapid Prototyping process. From importing data to preparing platforms, RP professionals rely on the extensive tools in Magics for all of their software needs.

Complementary to Magics, our revolutionary Streamics™ product provides you with a user-friendly server based system which centralizes all of your customer project data, and which makes it easy to collaborate between your team-members and communicate with your customers.
Streamics™ can also help to automate repetitive or complex part operations (such as support generation, file fixing, and part labeling). Plus, there is a perfect and complete integration between Streamics™ and Magics..

Parts are created on a special machine layer-by-layer, and this unique process lets you – the product designer – add internal features like conformal cooling channels and lattice structures to reduce weight while preserving strength. Because the process is completely computer controlled, you are also able to modify features quickly and easily without additional expense, allowing you to test different versions of a prototype fast. Prototypes can be made in stainless steel, aluminum and titanium When combined with our CNC machining and finishing services, we have everything you need to create sophisticated prototypes for applications in medical, automotive, aerospace and other demanding industries.

When combined with our CNC machining and finishing services, we have everything you need to create sophisticated prototypes for applications in medical, automotive, aerospace and other demanding industries. 3D metal printed prototypes SLA & SLS Rapid Prototypes SLA & SLS are two of the original 3D printing processes. These methods are ideal for making rapid, one-off prototypes in plastic. These prototypes can be used as-is, or to function as master patterns for polyurethane vacuum casting. 

Like with other 3D additive manufacturing processes, you can add complex internal features that can’t be made conventionally. Polyurethane Vacuum Castings Polyurethane vacuum casting is a rapid prototyping technique suited for making up to 30 copies of a master pattern from a silicone rubber mold. The level of detail and surface finish of the copies is dependent on the quality of the master pattern. You choose the casting compound to match your design idea – hard or soft, colored or clear. 

We even offer overmolding to combine two or more different types of material in a single finished casting. The next two photos are considered reversed polarized (RP-SMA). We have a team of specialists who are experts at preparing master samples for casting. Samples can be provided by you or we can make them using CNC machining or one of our 3D printing services such as DMLM, SLA or SLS

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 


Molding Plastic Machines Injection molding is the most commonly used manufacturing process for the fabrication of plastic parts. A wide variety of products are manufactured using injection molding, which vary greatly in their size, complexity, and application. The injection molding process requires the use of an injection molding machine, raw plastic material, and a mold. The plastic is melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final part. The steps in this process are described in greater detail in the next section. Injection molding is used to produce thin-walled plastic parts for a wide variety of applications, one of the most common being plastic housings. Plastic housing is a thin-walled enclosure, often requiring many ribs and bosses on the interior. These housings are used in a variety of products including household appliances, consumer electronics, power tools, and as automotive dashboards. Other common thin-walled products include different types of open containers, such as buckets. Injection molding is also used to produce several everyday items such as toothbrushes or small plastic toys. Many medical devices, including valves and syringes, are manufactured using injection molding as well
