Aluminum Casting is Spreading

As die casting products widely used in automobiles, commodities, yachts and other important components, which, everyday, people will come into contact with these products.
Compared to other metal materials, the usage of aluminum casting seems more widely. Some aluminum die casting method like plaster casting, permanent mold casting and sand casting etc, is welcomed by the casting manufacturers, for its strengths in fields of price and qualities,          
When it considered the characteristics of some products, some requires like certain flexibility, precise size, and some individual design, this aluminum casting all can achieve. And through some practical examples, aluminum casting will be of some less defective and surface defects contrast others.

Why is Aluminum Die Casting Good?

Aluminum die casting is so popular in today’s market. Why aluminum is so welcomed?   And what is the advantage of aluminum die casting?

High quality of products is the important base for evaluating a manufacturing process. The parts made with die casting process, the shape of which is more complex and the forming request is high.    

Compared to some other production processing, aluminum die casting is also have the advantage. The production process of Aluminum die casting is easier and faster. And die castings are stronger and more stability in its size than plastic injection molding products.

Meanwhile, die casting is also environmental friendly, they are full of flexible, ultraviolet radiation and the faster pace in production.

HANGZHOU, CHINA  — Spurred by rapidly growing demand in China’s healthcare market, American specialty tubing extruder Precision Extrusion Inc. has opened a joint venture manufacturing plant in the eastern Chinese city of Hangzhou.

Precision, in Glens Falls, N.Y., has seen China grow from negligible sales levels five years ago to about 20 percent of the small company’s revenues, as the Chinese government has significantly boosted spending on healthcare, said Precision President Michael Badera, speaking in an April 16 interview at the China International Medical Equipment Fair, in Shenzhen, China.

Precision has a majority stake, while a Chinese investment firm Tong Xiang Peng Yi Ltd., in the city of Tongxiang, Zhejiang province, holds a minority position, he said, declining to disclose details of the investment or ownership stakes.

“It was a multimillion dollar investment,” Badera said.

The joint venture, which started production earlier this year, is called Hangzhou Peng Yi Precision Catheter Technology Ltd. The Chinese partner is a small privately-owned investment firm, Badera said.

The Hangzhou facility could eventually start to manufacture some of the company’s catheter balloons and have operations for applying lubricious coatings, which make the catheters easier to insert into the body, he said.

The factory is in the Hangzhou Economic and Technology Development Area, a giant industrial park outside the city. The park was helpful to Precision and provided the firm some grants to help defray rental costs, he said.

Badera also said the joint venture is considering expanding beyond components into producing finished goods and eventually doing an initial public offering.

Precision Vice President Rosy Wang, a native of Hangzhou and longtime employee of Precision, is the chairman of the joint venture.

The Advantages of Die Casting

Die casting is an efficient, economical process offering a broader range of shapes and components than any other manufacturing technique. Parts have long service life and may be designed to complement the visual appeal of the surrounding part. Designers can gain a number of advantages and benefits by specifying die cast parts.

High-speed production – Die casting provides complex shapes within closer tolerances than many other mass production processes. Little or no machining is required and thousands of identical castings can be produced before additional tooling is required.

Dimensional accuracy and stability – Die casting produces parts that are durable and dimensionally stable, while maintaining close tolerances. They are also heat resistant.

Strength and weight – Die cast parts are stronger than plastic injection moldings having the same dimensions. Thin wall castings are stronger and lighter than those possible with other casting methods. Plus, because die castings do not consist of separate parts welded or fastened together, the strength is that of the alloy rather than the joining process.

Multiple finishing techniques – Die cast parts can be produced with smooth or textured surfaces, and they are easily plated or finished with a minimum of surface preparation.

Simplified Assembly – Die castings provide integral fastening elements, such as bosses and studs. Holes can be cored and made to tap drill sizes, or external threads can be cast.
