Mold-Masters, the manufacturer of hot runner systems, mould bases and temperature controllers based in Canada, has expanded its production facility in Brazil and added new equipment, including CNC machining centres. This investment is intended to significantly increase Mold-Masters’ capabilities in the growing Brazilian market.

Mold-Masters is not new to the Brazilian plastics market, having opened the manufacturing facility in Sumaré, São Paolo state, in 2001 to better serve local and global customers. Since then, the company has seen its business there escalate, the rapid growth being driven by unprecedented product demand. The new facility expansion will enable Mold-Masters to continue to grow its business while enhancing value delivered to the rapidly developing Brazilian market.

Mold-Masters, as vertically integrated as any hot runner manufacturer in the world, can now provide not only exceptional regional support in Brazil but also enhanced local assistance for technical service, application engineering and rapid spare parts deployment.

“With our focused commitment to providing solutions, service and support globally, together with the economic growth in Brazil and South America, the facility and services expansion will provide the local, regional and global support needed to meet our customers’ needs in Brazil,” explains Douglas Hugo, Mold-Masters’ VP of sales and service for the Americas.

“This manufacturing expansion, paired with a new global quality standard on manufacturing processes of hot runner systems, mould bases, and temperature controllers, shows how important the Brazilian and South American market is for Mold-Masters,” adds Robson Gonçalves, operations manager for Mold Masters Brazil.

Injection molding is a manufacturing process, which is making semi-finished parts of certain shapes by pressurizing, injecting cooling and separating molten thermoplastic.

The independent research company CIMdata Inc. published Version 14 of its “NC Software and Related Services Market Assessment” in June. This market report provides information about the worldwide market for numerical control software products and services. SolidCAM was named in this year’s report as the most rapidly growing CAM vendor in the world in 2004. The company experienced growth of 51.1% last year.

“We’re pleased that CIMdata is projecting SolidCAM to be the fastest-growing CAM software vendor again in 2005,” says SolidCAM chief executive officer Emil Somekh. “Our estimated growth rate is 41%.”

SolidCAM has been experiencing steady significant growth since the start of 2003, when the company achieved Certified Gold Partner status as the seamlessly integrated CAM engine for SolidWorks.

The SolidCAM+SolidWorks bundle is giving SolidCAM resellers a powerful competitive tool in the global CAD/CAM market. SolidCAM’s expansion continues worldwide. For example in the Asia-Pacific region, SolidCAM now has resellers in China, Hong Kong, Taiwan, Singapore, Thailand, and Malaysia.

A copy of the CIMdata NC market assessment, including two charts, is available at

SolidCAM2006, Release 10 of the package, which will be presented during EMO Hannover (Hall 15, Stand E 63), should be the basis for more growth. The new release includes many improvements, new functions, and major performance enhancements. It is integrated in SolidWorks 2006.

The largest and most influential trade fair of its type in Asia, Chinaplas 2006, the 20th International Exhibition of the Plastics and Rubber Industries, will be held April 26–29, 2006, in Shanghai, at the New International Expo Centre, Pudong. This regional must-attend event for industry professionals is certain to break records for show scale, internationalization, and visitor recruitment.

The show will occupy an exhibition area of more than 90,000 m² and will showcase more than 1,300 exhibitors from around the world. It is expected to be over 50% larger than the previous Shanghai show in 2004. Already, more than 80% of the exhibition area has been reserved or confirmed; both established exhibitors and newcomers have indicated strong interest in participating in the event.

Many international companies are investing in Chinaplas 2006, including the plastic technology and chemical giants. Austria, Canada, Germany, India, Italy, Japan, China, Taiwan, the United Kingdom, and the United States will have large-scale national pavilions.

To facilitate interaction at the show, Adsale Exhibition Services Ltd., the organizer of Chinaplas 2006, has created eight theme zones for visitors: the Chemicals & Raw Materials Zone, Machinery Zone, Drinktec & Plastic Packaging Zone, Auxiliary & Testing Equipment Zone, Die & Mould Zone, Rubber Equipment Zone, Semifinished Product Zone, and Chinese Export Machinery Hall. Chinaplas 2005 in Guangzhou was attended by some 52,000 quality buyers, 7,921 of them from 79 countries or regions outside of China. Concurrent symposia and a conference will be another attraction for Chinaplas 2006 visitors.

For the 17th consecutive year, Chinaplas will enjoy the exclusive sponsorship of EUROMAP (the European Committee of Machinery Manufacturers for the Plastics & Rubber Industries) in China. Chinaplas 2006 is co-organized by Messe Dusseldorf China Ltd., the China National Light Industry Council—China Plastics Processing Industry Association, Shanghai Society of Plastics Industry Association, and International Trade Promotion Corp.

With eight months to go before the doors open to visitors attending the MACH 2006 trade fair, the premier UK manufacturing technologies event, 90% of the exhibition space in Hall 5 of the Birmingham NEC is already sold, with sales for the other floor in Hall 4 following at nearly the same pace. The Manufacturing Technologies Association (MTA), which is organizing the show, is well on the way to achieving its goal of selling 26,000 m² to more than 500 exhibitors.

Sales throughout August and into September were strong. Commented Graham Shearsmith, exhibition manager: “I’m delighted with the response we’re getting to our sales campaign, which has been focused on giving exhibitors the best deal possible from the start. “Our latest change in this area is that we will be opening up a walkway at the back of Halls 4 and 5 to allow a more even movement of people between the halls, rather than all the traffic having to use the stairs at the front of the halls.”

Confirmed exhibitors now number 360. Up-to-date floor plans and a revised exhibitor list are posted at the MACH 2006 website every Friday afternoon.

MACH 2006 encompasses metal-cutting and metal-forming machine tools along with ancillary and related products and services. The event introduces MACHplus, exhibitors from related industries, and MACHconsult, a source of informed advice from industry experts. The show has recently attracted more than 400 exhibitors and in excess of 20,000 visitors.

Running from May 15 to 19, 2006, the event will in effect be much larger by virtue of the colocation of several smaller, related fairs at the NEC during that week. The simultaneously held fairs include Subcon, Weldex, Drives and Controls, Electrex, and Airtech.

The new name for the North American distribution operations of the steel production mill Edelstahl-Witten-Krefeld GmbH (EWK), effective October 1, is Swiss Steel International NA. Formerly known as ThyssenKrupp Specialty Steels NA, the distributor underwent the change in identity as a result of the sale last May of EWK and its international sales subsidiaries to Swiss Steel AG of Emmenbruecke, Switzerland.

The integration of EWK into Swiss Steel will create the world’s largest steel production, distribution, and processing company for long products, according to Tony Elfstrom, president and CEO of Swiss Steel International. “The combination will result in investments in product offerings, customer service capabilities, and value-added services that will benefit our customers,” he said.

“However, there will be few changes in our day-to-day operations, other than introducing a red-and-black logo and answering the phones with ’Swiss Steel International.’”

The new group will have 7,500 employees worldwide and a total steel production capacity of 2.5 million metric tons, with annual sales of $4.1 billion.

Elfstrom reiterated that the sales and marketing team would not change, nor would the source and mixture of products. “Our tool steels will still be produced by EWK in Germany, and we will continue to provide nonferrous tooling materials supplied through our distribution partners Alimex, Alcan, and Brush Wellman. Plus, our Heat Treatment Division will continue to provide the highest-quality vacuum heat treatment, metallurgical lab services, and technical support.”

One benefit of the new organization will be increased production output with shorter lead times. Elfstrom noted that this is because EWK has received supervisory board approval to invest $150 million in current production facilities.

Swiss Steel International NA has operations in Cleveland, Chicago, Detroit, and Minneapolis in the United States and Toronto and Windsor in Canada. Swiss Steel AG is a globally active steel group owned by the Schmolz & Bickenbach Group of Düsseldorf, Germany, with branches on every inhabited continent. is open for business.

Depo Frästechnik of Marienfeld, Germany, a manufacturer of high-quality milling machines and cutters, and NC Graphics (Cambridge) Ltd. of the UK, a software house specializing in CAM software for high-speed manufacture, have concluded a new agreement to continue joint development and exploitation of their CAM package, DepoCAM.

To further strengthen distribution, the brand names “machiningStrategist” and “NCG,” previously used in some sales territories, will be dropped in favor of “DepoCAM.” This will allow DepoCAM to become a globally recognized name. In each territory, one strong distributor will offer not only DepoCAM but also the benefits of the full range of advanced milling technology products pioneered by Depo.

Live cutting trials and benchmarks are available from Depo’s demonstration center at Leamington Spa, England. All DepoCAM installation, training and customer support will be provided from NC Graphics’ offices near Cambridge. An eight-person sales team will cover all regions of the UK offering the Depo products, consultancy and support to a combined user base of over 500 precision-engineering

What is More Convenient the Regular or Rapid Injection Molding

Plastic molding has been known as the most popular way of processing and creating plastic. There are three types of molding machines that is commonly used by most of the industrial companies nowadays. These are the electric, hydraulic, and the hybrid but there are two main processes that can be used in processing plastic these are the regular way and the rapid injection molding.

The regular way of injection molding involves the process of pouring plastic granules into the hopper and it slowly passes into the barrel where it is being heated and melted. The large screw passes the melted plastic into the mold where it is being cooled and finally hardens. Once the plastic has been solidified it will be ejected from the mold. However, the rapid injection molding uses the method of prototyping and conventional injection molding.

Compared to the regular process, the rapid injection molding is cost-effective and of course fast that will allow you to fix any problem encountered if the product design is not right. It uses an aluminum mold, which is unlike the hardened tool use in the regular process. The molds used in rapid injection molding consists of the A-side, which is also known as the cavity side, and the B-side, also known as the core side.

When choosing a design that will be used in the rapid process, make sure to avoid adding small features into the steep walls. Similar to the regular process, it is important that the mold has enough thickness that is equally distributed to avoid any damage into the product. There are different parts that are made from rapid injection molding and an example of this are some of the medical devices that is being used by most of the medical companies. medical companies need the medical plastic molding parts for the business as well.

Both of the processes have their advantages, but the best thing that you must do is to choose the one that will best meet to your needs.
