The New Diamond Lux Line: the turnkey solution particularly suitable for molding surfaces with high thermal and aesthetic requirements

(PresseBox) ( Hong Kong, )
The INglass-HRS Flow group will participate in CHINAPLAS 2013, the 27th International Exhibition on Plastics and Rubber Industries, which will be held on May 20-23, 2013 at China Import & Export Fair Complex, Pazhou, Guangzhou, PR China.

The new line from HRSflow was developed for PC applications that require high aesthetic quality such as Front Headlamps and in the Plastic Glazing market for the manufacturing of large injection-compression transparent surfaces.

HRS's twenty years of experience has allowed us to develop a new hot runner system line called Diamond Lux, particularly suitable for molding PC components that require high aesthetic qualities. This line is suitable for molding any Front Headlamp components for the automotive industry: Housings, Bezels and especially for lenses molded in PC or PC-HT.

This new line finds its perfect application also in the innovative Plastic Glazing sector where Quarter Windows and Panorama Roofs formerly manufactured in Silica Glass are now molded in Polycarbonate by using the multishot tecnology to integrate locating and mounting features.

This new technology is beginning to establish itself in the automotive market which is made possible thanks to "injection-compression" which INglass-HRSflow holds numerous patents worldwide.

In the new Diamond Lux Line, particular attention has been dedicated to the thermal optimization of hot runners - the fundamental factor that affects the aesthetics of the molded part. The objective was achieved by insulating the plates from the mold using spacers with low thermal conductivity and paying particular attention to the power loss in the thermal bridges. All contacts towards the mold were geometrically optimized in order to reduce the thermal power dissipation and were made of materials with low thermal conductivity.

The heaters are symmetrically placed in the top and bottom of the manifolds to reduce cold zones and high residence time. The screwed-in nozzles do not allow any contact with the mold except for the tip area.

Nozzle thermal control is optimized thanks to the use of special brass sleeve heaters. Each heater is dedicated to the thermal control of the gate zone and this ensures a more precise and steady process control. The brass also allows standardizing the thermal profile thanks to its high thermal conductivity.

These technical solutions ensure a more constant temperature, with a tolerance of + / - 10oC across the entire system. The customer is provided for each system the thermal analysis of the manifolds to show how the temperature consistency is reliable.

The nozzle is fully protected by a stainless steel protection tube that assures both a homogeneous distribution of the temperature by reducing thermal dissipation and at the same time acts as a guard to the thermocouples wires.

The nozzle design was also changed to minimize cut out pocket space in the injection area.

All the hot runner internal channels are engineered to avoid stagnation spots that could cause unacceptable defects in crystal clear lenses.

Special shaped plugs have also been implemented to further avoid any stagnation close the valve gate pin.

The tip and end rings geometry and material used to produce them, have been selected to optimize the temperature in the gate area. Special attention was therefore paid to the quality of injection point/vestige into the molded part.

Furthermore they have been designed to have an excellent performance even with high injection pressures.

Finally the entire hot runner is made of a special steel with a coating able to void polycarbonate degradation, thereby preventing the risk of unaesthetic black spots on crystal clear applications such as lenses and window panels. The result is less rejects and higher productivity.

Excellent piece quality and less waste: give yourself the luxury of buying the best and your choice will be paid back!


INglass is a globalized group dedicated to the designing and production of molds for the automotive field and hot runner systems for all industry solutions. It was founded in 1987 by the will of the President, Maurizio Bazzo specializing in making molds for car lighting. HRSflow was born in 2001 for the production of hot runner systems. In 2005 was created the INglass plastic glazing division for the production of molds for wide surface made of polycarbonate instead of glass. INglass is able to successfully consolidate its market position by presenting not only as a mere supplier of hot runner systems, but as a partner able to provide expertise and advanced solutions during the whole plastic molding process. The production systems and the designing system are at the forefront of the latest technology, meeting the standard UNI EN ISO 9001: 2000 to ensure the highest quality products.

About CHINAPLAS 2013

CHINAPLAS 2013 is organized by Adsale Exhibition Services Ltd. and China Foreign Trade Centre (Group), and co-organized by the China National Light Industry Council - China Plastics Processing Industry Association, China Plastics Machinery Industry Association, Guangdong Plastics Industry Association, Messe Düesseldorf China Ltd., the Plastic Trade Association of Shanghai and Beijing Yazhan Exhibition Services Ltd. The event is also supported by various plastics and rubber associations in China and abroad.

First introduced in 1983, CHINAPLAS is China's only plastics and rubber trade show approved by UFI (The Global Association of the Exhibition Industry). CHINAPLAS has been exclusively sponsored by the Europe's Association for Plastics and Rubber Machinery Manufacturers (EUROMAP) in China for the 24th time. It is currently Asia's No.1 and world's No.2 plastics and rubber trade fair. CHINAPLAS 2013 will cover over 220,000 sqm of exhibition area. More than 2,900 exhibitors from 38 countries and regions, together with 14 pavilions from Austria, Canada, France, Germany, Italy, Japan, Korea, PR China, Taiwan, Singapore, Switzerland, Turkey, UK and USA will showcase their diversified chemicals and raw materials and over 3,200 sets of plastics and rubber machineries. The 4-day exhibition is expected to attract over 115,000 trade visitors from 150 countries or regions. Online pre-registration is available now till May 16, 2013. Pre-registered visitors will enjoy free admission and free coupon to redeem the exhibition catalogue. For more details, please visit the official website at
