Kistler and STASA develop an automatic method for the prognosis of injection molded part quality

Swiss company Kistler Instrumente AG of Winterthur is the leading international supplier of sensors and systems for in-line cavity pressure-based quality monitoring of injection molding processes. German specialist Steinbeis Angewandte Systemanalyse GmbH (STASA) with headquarters in Stuttgart has many years of experience in the development of process models, online prognosis of quality features based on characteristic process values as well as the application of complex mathematical methods and models to industrial processes. This expertise is based on scientifically corroborated methods such as the design of experience (DoE) and the generation of models, and can be reliably applied to injection molding.

The implementation of approved Kistler systems into process-related quality monitoring of injection molding processes based on process profile characteristics such as the properties and tolerances of the cavity pressure curve is already widely established. Kistler and STASA have now joined forces to develop an enhanced quality monitoring method for injection molding processes that allows the direct quality monitoring and definite prognosis of the quality of the currently molded part by using the quality models of the STASA QC program. Based on the process models and measured process parameters, the final dimensions of the molded part can be predicted online, i.e. while the part is being produced. Immediately after injection molding, this approach provides information on whether the part will meet specified dimensional tolerances when it is used.

The new concept has many benefits for manufacturers and OEMs of injection molded products: they will receive information on the tolerance limits directly from the part specification and can use this criterion as a parameter of the process monitoring system. This technique significantly enhances in-line quality monitoring of injection molding processes: the limits of monitoring parameters such as pressure maxima, pressure integrals and other values need no longer be defined and evaluated. Instead, the relevant correlations between process profiles and quality criteria are acquired during mold sampling and are then used for process monitoring. The DoE used during mold sampling has beneficial side effects, because the injection molding process can be optimized automatically and ideal parameters for meeting the required quality criteria can be defined within the process latitude.

This combination of process and quality monitoring with quality prognosis has long been requested by molders of high-quality, extremely sensitive, hard-to-assemble moldings such as producers of medical parts and pharmaceutical components. This technology is integrated into Kistler CoMo Injection process monitoring systems as an optional module. Quality prognosis will become available as a high-end option for the CoMo Injection during the course of 2011.

Background: Quality Assurance with Mold Cavity Pressure
The cavity pressure curve is considered to represent a fingerprint of the injection molding process. It is the most informative characteristic for evaluating the quality of the part. Deviations from the optimum curve are clear indications of process fluctuations that lead to part defects ranging from incomplete mold filling to flashing or dimensional discrepancies. As the supplier with the largest and widest range of sensors for all methods of injection molding, simple connection technology and intuitively easy to operate, networkable systems, Kistler is the only manufacturer to offer complete monitoring of injection molding from a single source. Kistler is the world\'s leading manufacturer of pressure and temperature sensors for use in the plastics processing industry

Rajoo Engineers Forges Ahead; Technical Collaboration With Hosokawa Alpine Ag

The markets in India and parts of Africa, would benefit immensely with this collaboration. It would bring the very best in blown film technology of HOSOKAWA ALPINE through one of the most trusted and respected names in the business – Rajoo Engineers.

The maxim ‘Excellence in Extrusion’ continues to drive Rajoo Engineers and thus the technical collaboration with HOSOKAWA ALPINE AG of Germany – one of the most reputed companies globally in this sector – comes as no surprise.

Both companies are long-established manufacturers of blown film lines. The HOSOKAWA ALPINE lines are used around the world by customers with high quality and performance demands. The RAJOO systems cover the demands in many newly industrialised countries such as India, Africa, Gulf and parts of Latin America and have their main focus on an attractive price-performance ratio for the customers.

The markets in India and parts of Africa (Nigeria, Ghana, Kenya and Tanzania), would benefit immensely with this collaboration. It would bring the very best in blown film technology of HOSOKAWA ALPINE through one of the most trusted and respected names in the business – Rajoo Engineers at affordable price levels.

In a first step, Rajoo Engineers Ltd. will assume responsibility for marketing and service support for Alpine’s blown film systems in India as well as in Nigeria , Ghana, Kenya and Tanzania. Both companies plan to jointly develop a new product line of blown film systems. It is planned to combine the time proven machine components of both manufacturers to form new hybrid systems on a higher quality level and at a simultaneously attractive price levels.

In future, this joint venture will be extended to include co-operation in the areas of service support, development, production, joint procurement and sales and marketing.

‘Rajoo’s strong understanding of the developing economies coupled with world class technology of Alpine will ensure a unique mix that customers would benefit from, says Sunil Jain, President, Rajoo Engineers. ‘The brand and the network of Rajoo will only raise the bar of customer satisfaction’, he adds. This alliance with ALPINE would only further the focused efforts of Rajoo in blown film lines, an area where the company enjoys premium market position.

‘Synergies will result from this cooperation in the areas of international marketing, production and procurement as well as in joint product development. For Alpine, this collaboration would also serve as an extension of its manufacturing capability, wherein it could now source from India, aggressively priced blown film solutions (using its technology and manufactured by Rajoo Engineers), for its global markets.’, says Peter Krieg, President, Hosokawa Alpine AG.

The existing Rajoo portfolio of the widest range of mono and multilayer blown film lines up to seven layers, sheet lines up to five layers, water quenched downward extrusion lines up to three layers, lines for foamed film and sheets for various special applications and thermoformers will now be supplemented by hybrid products as well as complete ALPINE systems, giving the customer enough options to choose from.

About Rajoo
Based in Rajkot, Rajoo Engineers Limited, having made a modest beginning in 1986, has today emerged as an undisputed global player in blown film and sheet extrusion lines. Owing to its focused efforts in blown film and sheet extrusion lines, the Company enjoys premium market position in this segment. Being a technology driven Company, product innovations, world-class quality, state-of-the-art workmanship, increased energy efficiency and high levels of sophistication and automation have become the hallmark of Rajoo products during all these years, positioning the Company\'s products on a global platform, competing with the established world leaders.

RTP opens second engineering compounding plant in Europe

Engineered thermoplastics compounder RTP Co. has opened a new manufacturing plant in Ladenburg, Germany, the company’s second in Europe. 

Operating as RTP Deutschland GmbH, the 61,500-square-foot operation will make products including very long fiber composites and conductive compounds.  “In addition to expanding manufacturing capacity, the Ladenburg plant also houses on-site product development engineers as well as a quality assurance laboratory,” said John Van Wijk, the company’s European director of sales, in a news release. 

RTP now has 11 manufacturing sites. Other locations include Beaune, France; Suzhou, China; Singapore; Monterrey, Mexico, and six plants in the United States.  RTP bought the Beaune plant from French thermoplastics compounder Codiplast SNC in 1995. Since then, RTP has significantly expanded its global footprint. The company said a second plant in Europe was necessary because of growth in its market for engineered materials.
