Aluminum Die Casting

Aluminum Die Casting Description:
Aluminum Die Casting, Die casting is similar to Permanent mold castings except that the metal is injected into the mold under high pressure of 10-210Mpa (1,450-30,500) psi . This results in a more uniform part, generally good surface finish and good dimensional accuracy, as good as 0.2 % of casting dimension. For many parts, post-machining can be totally eliminated, or very light machining may be required to bring dimensions to size. die casting,aluminum casting can be done using a cold chamber or hot chamber process.

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.

Plastic Molding Manufacturing

Plastic Molding Manufacturing & Design

Many projects have come to us without the ability to manufacture the product the way the customer had intended. Largely due to the customers lack of knowledge in the plastic molding manufacturing processes when it come the plastic injection molded. Several projects have been renewed when it was discovered by our engineering department that the mold had been gated wrong and this lead to the part having too much stress molded into the part for the finished product to survive in its intended environment.

We pride ourselves in helping the customer by becoming involved early in the process of product design to help prevent end use product failures. One of our best customers asked us to bid on a project that others had already submitted their bids and the customer was complaining about not understanding what made the project so costly. We decided that before we would submit a bid that we would have to sit with the engineer at our customers facility and find out what the expectations were and see if we could find a way to help reduce the cost. As it turned out all that was needed was our engineers to sit with their engineers and we discover that one wall sections in the very complicated part, needed to be moved slightly so that the part did not have an undercut section requiring a side-core in the mold. The customers’ engineer had no problem with the slight modification which as it turned out was all it took to make the part cost justifiable. We got the order.

As we followed up on the sales engineering visit that produced this order we asked why such an obvious change had not been seen before we showed up in their engineering department. The answer was, “because you were the only people that bothered to show up and ask the questions and sit with our engineers.”

We like early involvement. We know how to make a product more manufacturability.

Advanced Quality Planning (AQP)

The ultimate objective of the Advanced Quality Planning system is to launch new plastic mold and plastic products with designs and mold and molding manufacturing processes that insure all cost, quality and delivery expectations of our customers are met. Cross functional teams who use checklists, question/action plans and team inputs to develop Process Flow, FMEA, Process & Inspection sheets, and tools and gauge plans accomplish this. The cross-functional teams consist of representatives from all of our internal departments and the customer. They make use of the best practice manuals, quality history and error proofing to identify the design and process that will provide zero defects at competitive prices.

Sample Submission/Dimensional Layouts

This discipline is responsible for PPAP scheduling, Project Management and complete PPAP certifications of all new and changed plastic parts per the AIAG PPAP requirements Dimensional layout of all plastic mold and plastic molding products is accomplished using traditional equipment as well as state-of-the-art measuring equipment, such as CMM analysis.

 

Plastic Mold

Plastic Mold & plastic Molding

Several years ago we were in 2 business models. One was Plastic molding and the other was plastic  mold building. Shortly after the Chinese became a threat to our tooling or mold building industry we decided that we needed to pick one business model or the other. We decided that we would best serve our stockholders by choosing to be a manufacturer of plastic injection parts of a nature that we began to call “Crazy Jobs No One Else Will Do”.

Therefore we were no longer in the Plastic mold building business as a primary function to our end goals. What we have become is responsible for all the mold construction that we sell to our customers that is the means to the end better known as a finished plastic product. We turned our mold building facilities into a production machining line for value added services to the plastic products. We use our machining facilities to finish machine dimensions to the fourth decimal in plastic parts.

Now when it comes to building plastic mold what we now offer is much more valuable than we ever could have offered. We work with several highly qualified plastic injection mold builders around the world including China, Taiwan, Germany and England to get the customer the best possible mold to suit the application requirements. We take full responsibility from start to finish. Here is what we offer:

1) Tool design knowledge that will help us pick the best mold building facility
2) Tool construction project management.
3) First article testing and final approval of all dimensions to meet the customer’s requirements.
4) Free tooling maintenance for the life of the tool as long as it stays at PMT.

One stop shopping for the entire process. We will make sure you get off on the right foot from the start of the product design all the way to getting the parts through first article approval and ready for production.

Metal Casting

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.

Die Casting Process

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

Casting Mold Technology

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.

Aluminum Motorcycle Parts

One of the best reasons to get an aluminum motorcycle hitch carrier is because they are so reasonably priced. Compared to a standard trailer, they are much more affordable and do the same job. As long as you only need to carry one motorcycle, you simply don’t need a large trailer. A hitch carrier provides plenty of room at a fraction of the price.

You may be wondering-why Aluminum Casting? While there are other types of materials available in hitch carriers, there are many reasons to choose an aluminum motorcycle hitch carrier. Aluminum is just as strong as other types of metal. But it is also much lighter than almost any metal available today. That means you won’t be wasting gas towing the hitch carrier, you’ll only be towing your bike. Aluminum won’t add extra weight to your car, truck or SUV. Read more
