Zinc Die Casting

We have been in the foundry business since 3 generations and are proud to keep this going. Our chairman Dr. Dinesh Patel founded the company Dr. Dinesh and Ramesh Eng. Pvt. Ltd. in Ahmedabad. The company covers a space of 10,000 sq. yards (comparable to cricket field) which is only 40% utilized giving us an undue advantage for growth. We have had several metal castings (Cast Iron, Stainless Steel, Aluminum) catering to International and Domestic Companies like Ingersoll Rand, ABB, TVS and many others. However, since a decade we have shifted our focus primarily on Aluminum Castings producing from 0.5 kg to 100 kg in permanent mold. We have been adding new processes such as 

a) GDC (Gravity Die Casting)
Gravity Die Casting is the process of pouring liquid metal using Earth’s Gravity and hence it’s name. This method started on our end based on our customer’s demand leading us to develop a very difficult casting weighing almost 70 Kg in Permanent Mold for a German Company. Very few foundries can design this size of casting much less make it export quality. We are proud to say that soon we designed another such casting thereby establishing our niche in higher weight category giving an undue advantage for people with quality requirements in heavy castings. 

b) Tilt Pour
In order to satisfy the demands of our customers from around the world as well as in the domestic market we developed the Tilt Pour technology providing, engineering as well as aesthetic parts. Due to our in house building of the machine we have significant control over machine. This helps to significantly improve the quality and speed of casting manufacturing as the functioning of the machine can be customized over several parameters. Final result – better lead times and consistent quality. 

c) LPDC (Low Pressure Die Casting). 
Our goal is to keep on adding newer technologies and keeping in line with this principle we added the LPDC technology to our belt. Often when X-ray quality castings, dynamic movement (high r.p.m) is a requirement or some other quality standards dictate the usage of LPDC. 

In terms of our production capacity we have 
Production Capacity: 2000 tons per year 
Melting Furnances: 2
Holding Furnance: 5

Plastic Chair Mould

Plastic Chair Mould

Plastic Chair Mould is needed every where on the world, but how ti purchase a good quality plastic chair mould from China mold companies  is not easy thing, normally all of  China Mold Makers can make Chair mould, but you need ti need to very carefully  to select your supplier,Please ask below questions to the mould company to see if they are good or not.

Quality points we need to take careful during Chair Mould Making

1, Can you tell your chair mould running cycle time?
If the cooling water temperature is from 8 to 12 centigrade degree, if the chair weight from 1700g to 2400g, the cycle time should be 35s to 50s. If the machine plastic melt and injection is with accumulators. Please check how they make the cooling channel? If the cooling channel is extra in and out? If the cooling channel is one according with the chair shape?
2, How you guarantee your chair mould run shorts?
The guarantee for a mould runs 1 million shorts without any flashes? Because if you accept to cut the flash by your workers, I think you can use this mould for 10 millions shorts. So you need to check the steel hardness, and in the mould if there is any parting area were welded. Normally the steel hardness should be HRC33.

3, How you make the parting line finishing is good, if there is any sharp edges?
Sharp edge on the chair is dangerous, in order to avoid the sharp edge, we have to do many points during the chair mould manufacturing.
– Chair mould parting design is correct or not.
– The chair mould cavity and core thickness is enough or not.
– How you make the CNC milling the cavity and core? Normally, we need 3 stages finishing. From rough milling to steel hardened, after hardening, take the 2nd stage milling, we call it half precise milling, normally we leave 0.3mm, Then make the steel stress releasing, after this we do final precise milling. When in this time, the machining operation is very important.

1). we have to use cooling on the milling area. 2). we have to be sure that each cutting, the depth will not bigger then 0.08mm. All these are because of the steel will be deformed when milling and after the hardening. The deforming will cause the cavity and core’s fitting are not accurate, there will be a lot of hand works on it. By hand works on the parting area, you can never work out a perfect parting line.
4, the wall thickness is even or not.
Hand working on the parting line also be one of the reasons for wall thickness is not even. Of course, most of the reason is from the plastic chair 3D design and poor polishing on the cavities and cores. So when we start a plastic chair design, we have to consider the wall thickness. Some time, we need to make some area a little thicker to be sure that the chair is strong enough. But we have to consider seriously when it is need. because the uneven thickness will caused the injection not balanced and also will caused the cooling time not even. This will affect the injection speed slow down and also will cause the shrinkage marks. If the CNC milling is too rough, you can never get a chair with thickness even.
5, how about the stackable?
When the chair plastic designs are doing, we have to check its stack ability. And you also need to consider the deform possibility of the chair molding.
6, how you can make the Plastic chair mould with less weight but strong enough?
When starting makes the plastic chair design, we have to consider the weight and the strength. You can make the bottom area be strong enough by add more ribs. But how about the leg, backrest and armrest area? For this reason, you need to calculate or analyze the force of each area…in order to make a light chair strong, you can choose a very low MFI PP material. But in this way, you need to make the mould very strong and also you need to be sure the injection filling are available, as because you are using a material with MFI 4 or Max. 6.
7, How to make the air venting on the chair mould backrest?
For some chair backrest design is very complex, there is a lot of material jointing line, and some air cannot venting out when material filling and flowing. For this reason, you need to analyze by mold-flow maybe, and there are a lot of area need air venting built in the chair mould.
8, how to keep your chair mould finishing long lasting?
In order to make your chair mould cavity and core will not be rust by the plastic material, you need to be sure that the steel are high chrome and also the hardness are bigger then HRC33. If you will use some recycled material for injection, you need your chair mould be hard chrome plated. Otherwise, you need to make the polishing from time to time.

HYX  is the leading plastic chair mould manufacturer in china, we has developed more than 300 sets chair moulds during these years. We are also professional in PC transparent chair mould gas injection. If you need a high speed, long time and nice finishing chair mould, please come to us. We are sure you will be satisfied.

Different Types Of Casting To Suite Your Casting Necessity

There are different processes that can be used in creating complex shapes of metals parts and one procedure is through casting. Casting is a manufacturing method wherein a liquid material is transfer

red into a mold, usually following a hollow cavity of the desired shape, and then allowed to solidify afterwards. It has been used even in the past and one example or type of casting is die-casting.

The die casting method is a process of forcing molten metal under high pressure into mold cavities similar to permanent mold casting. It best suites the purpose of making small to medium sized parts fashioned with good and precise details. By-products of this method are furnished with fine exterior finish and dimensional accurateness. Most materials used in this method are metals such as zinc die casting, copper, and aluminium die casting and magnesium die casting.

Another form of casting which is considered to be the most popular and simplest type is sand casting. It is a technique that has been used for many centuries now. Sand casting is a process of forming a mold out of a sand mixture through pouring a casting liquid into a desired shape. This type of casting allows manufacturers to create large number of products in such a small range of production expenses. Most metals are caste depending in the type of sand used for the molds in this method.

An additional process that can be also used is Plastic molding. It is a manufacturing technique in making parts from both thermoplastic and thermosetting plastic materials for production. It includes plastic injection molding wherein molten plastic is injected at high pressure into a mold, which is the opposite from the product’s actual shape. Example by-products of this method are bottle caps and outdoor furniture.

Moreover, a further technique is cold forming. It is also known as cold forging. Cold forming is a manufacturing procedure in which a metal is shaped at an ambient temperature to produce metal components in a definite shape. The techniques usually involved in this procedure are bending, cold drawing, cold heading, coining extrusion, thread rolling and others.

Some benefits of cold forming are enhancements in the component properties of the product because the grain structure of the material is being elongated during the formation process wherein it is forced to follow the structure and as a result its’ strength is increased. Another benefit of cold forming is that the aesthetic finish of the components gives out a brighter facade and formed with a consistent high tolerance. These somehow reduce the necessity of complex finishing and polishing.

These are only some of the different kinds of casting. Other types of casting aside from die-casting, cold forming and sand casting of metals are plaster casting, shell molding, investment casting, permanent mold casting, centrifugal casting, continuous casting and casting of plaster, concrete, or plastic resin. Each type of technique has specific and unique routine that allows you to produce superior outcome and high-quality by-products to best suite all your casting needs for your manufacturing use.

What Is Casting?

Metal casting is an ancient technique that has a variety of applications and purposes. Civilizations from the dawn of time to present day have used metal working as a way of creating artistic, religious, and practical items. The process of metal casting involves melting metals at high temperatures and using molds to then shape the metal into new items. The furnaces used in metal casting helped pave the way for the Industrial Revolution, without which the course of history would be dramatically different. Metal casting is just one form of metal working that has seen a recent surge in popularity as resources are becoming more affordable and communities are springing up to share information, ideas, and projects.

The characteristic of die casting

Pressure casting or casting, is a molten gold poured into the pressure chamber, to the high speed filling steel mold cavity, and the alloy liquid under pressure solidification and casting method. Die casting is distinguished from other casting method is mainly characterized by the high pressure and high speed. Metal liquid is under pressure to fill the cavity, and at higher pressure solidification under common pressure, 15 to 100MPa. The liquid metal to the high speed filling cavity, usually in the 10 – 50 meters / second, some still can exceed 80 m / s, ( through the gate into the cavity of the line speed gate speed ), thus the filling time is very short, about 0.01 – 0.2 seconds ( must be considered casting size different ) can fill the cavity. Die casting machine, die casting alloy and die casting is a casting production of the three elements, are indispensable. Read more

There are three main forms of Casting Mold failure

1 thermal fatigue crack damage failure

Thermal fatigue cracking failure of die casting production, mold repeatedly stimulated cooling and heating effect, the molding surface and internal deformation are involved, and the repeated cycles of thermal stress, leading to tissue structure of two injury and loss of toughness, causing cracks appeared, and continue to expand, once a crack expanding, and molten metal liquid impact, coupled with repeated mechanical stress crack accelerated expansion. Therefore, on one hand casting mold must be fully preheat starting. In addition, in the production of the die casting die in must be kept in a certain temperature range, so as to avoid the early cracking. At the same time, to ensure the mold production and manufacturing of internal no problem. Because of the practical production, the majority of the ineffectiveness of the die thermal fatigue cracking.
