Huron is famous for the company that developed the revolutionary double rotary milling head in 1890.

Huron was named after founder Pierre Philippe Huré. Early Huron products include both conventional and unusual designs of vertical and horizontal milling machines, backgeared and screwcutting lathes, horizontal borers and gear-cutting machines.

 

1880_Huron_Milling

[Pictured] Patented in 1880, this unusual Huron combination miller had separate horizontal and vertical milling units that shared a column able to be rotated so as to bring each into position over the table. The machine was built in four sizes, the smallest being man-driven by a pedal-operated flywheel.

REP International: the Most Genuine Name in Rubber Injection Molding!

Wednesday, 04 January 2017 by duke.lee

REP international (http://www.repinjection.com) is a World leader in rubber machinery with 100-year-old success story.  The REP company has been selling injection molding machines since 1948. Very early on, REP understood the importance of polymers and elastomers to industry and decided to specialize in the rubber injection technology.

REP’s distinguish itself from the competitions based of superior technologies

 

 

 

Closing Unit:

 pieddecalage_cale

The traverse castings of the frame have been specifically designed for each type of press to provide excellent rigidity. Deformation of the plates under load is less than 0.10 mm.  This special REP feature, combined with the shoulderless columns, ensures constant parallelism as well as exceptional tooling durability and guarantees the dimensional quality of the parts.

Injection Unit: 

zoom_injection

The Y-structure: is a proven principle. The separation of the plasticization and injection functions, associated with the regulation system, gives the entire injection unit unrivalled accuracy and regularity in the elastomer injection process.

For the same volume, the REP injection technique, with separation of the plasticizing and injection functions, means an injection plunger diameter 25% smaller than with the FIFO technique. For the same injected volume, the REP injection unit is twice as accurate as a FIFO injection unit.  Metering accuracy is further improved by programming the extruder to slow down before the set point is reached.

Cure Time Reduction Technologies:

http://www.repinjection.com/images/pdf/Turbocuretechnicalarticle_gb.pdf

TurboCure is a patented solution for improving quality and productivity while saving energy.   TurboCure reduces cure time up to 50% without compromising compound integrity.   TurboCure consists of TempInverter and FillBalancer modules, that can be applied together or individually depending on the application.  Turbocure can increase the average temperature of the material without the laminar effect.

By reversing the thermal distribution in the rubber flow, TempInverter reduces cure times up to 30%, providing 15 % energy-savings.  In the mould, by rebalancing filling between the cavities, FillBalancer modifies the distribution of temperature in the flow as far as the cavities and makes it possible to reduce the cure time by up to 40%.

The TurboCure solution was awarded several prizes: REP got the AFICEP”s innovation award in 2008 for TempInverter and Beaumont Technologies got the Best of Erie Award 2009 for Fill Balancer.

Energy Savings

Between 1997 and 2010, energy consumption on REP rubber injection molding presses was reduced by 70%.   Servo Dive & Drive is an electro-hydraulic solution associated to heat eco management.  It allows reducing significantly global energy consumption in the continuity of the efforts made by REP over the past 15 years.

BarregraphSDD

[Figure: Reductions in energy use on REP presses over the past 15 years]

Advantage of Servo Dive & Drive Technologies

  1. Low-energy consumption
    • Near zero water or powered fan requirement thanks to natural cooling of the pump
    • Reduced cycle time through better system responsiveness
  2. Improved Reliability
    • Optimal lubrication of mechanical parts
    • Very few parts in motion
    • Better aspiration
  3. Easy maintenance
    • No need to empty the tank
    • Oil-immersed servomotor-driven pump
    • Simple mechanism
    • Very few hydraulic hose

Electric Valve Gate Cold Runner Block

ServoBloc is an electric valve-gated cold runner block for rubber and LSR.  ServoBloc is suited to a large range of rubber compounds, soft to hard, from silicone to FKM, ServoBloc is fully integrated in your rubber injection press (retrofit is possible).

  1. Sequential diagnostic
  2. Closed loop control of the speed and position of the valves
  3. Gate size is a settable parameter
  4. No risk of oil contamination

The municipality of Heerbrugg is located where the Rhine flows into Lake Constance and Switzerland shares a border with Austria and Germany. Industrial history was written here: In the 19th century, a local brickworks developed a pioneering new production process. At the beginning of the 20th century, Heerbrugg became known as home to companies in the precision mechanics and optics sectors. Heerbrugg is still well-known today. Largely thanks to one of the biggest employers in the region: SFS intec.

 

Steady growth

SFS intec is big. This is confirmed not only by the headcount – more than 8,000 employees world­wide, including 1,400 in Heerbrugg – but also by taking an aerial view of the Heerbrugg site, the company headquarters. Standing on an area as large as eight soccer fields kare various buildings of different ages and appear­ance, bearing witness to the steady growth enjoyed by the company since it was founded in 1928.

 

Under very high pressure

Meticulously arranged in rows and marked off by yellow lines on the floor, close on 100 machines in the pressing plant hall produce 80 to 400 components per minute and machine, while creating an impressive volume of sound. In two to six stages, the machines form wires of 0.5 to 30 mm thickness into components – under very high pressure (up to 350 tonnes) and with no loss of material. The wire raw material is fed in at room temperature. This process is called cold forming. The formed components produced in this manner are then conveyed on for sec­ondary machining.

Metal-cutting with Mikron

Things are much quieter here, and it smells of machine oil. The machines in the secondary machining operations hall are much more compact than the ones used for cold forming. The arrangement of machines is no different: Everything is calculated down to the millimeter, and all small parts and tools have their own fixed place. “Here at SFS intec, when we talk of secondary machining operations, we mean all types of precision metal-cutting, such as milling, drilling and turning,” explains Harald Aspek. The 52-year-old operator is setting up a Mikron Multistar for the finishing of pressed blanks for the automotive industry. “We’ve had this Multistar for 13 years – I know it inside out,” adds Harald Aspek. SFS intec has been using Mikron machines (among others) for precision metal-cutting for over 30 years. Worldwide, there are currently a total of more than 30 machines in operation. Mechanical transfer machines – i.e. older Multifactor and Multistar models – account for the biggest share. The newest additions are CNC-controlled Mikron VX-10s.

Precise and fast

A journey by heavy load lift to the warehouse, where driverless forklifts are doing their rounds, and a short walk across the site road to the neighboring building take Roger Vauthier to his workplace. This is in another of the total of three secondary machining operations halls. There are Mikron machines in this huge hall as far as the eye can see. On each machine, SFS intec produces up to five million components a year, mainly for the automotive industry. “Versatility, very high cycle times and extreme reliability whatever material is being fed in: For me these are the advantages that Mikron machines offer,” says the 44-year-old operator. “And with the new VX-10s we can work with even greater precision and have shorter changeover times than with the Multi­factor,” adds team leader Harald Niederer (50). He has been working with Mikron machines since he joined SFS intec 17 years ago. “Mikron machines have enjoyed an excellent reputation at our company for many years,” Harald Niederer points out. “For instance, we also use them to train apprentices.”

 

Gray not green

There are more Mikron machines in the third secondary machining operations hall. In addition to machines from other manufacturers, this hall also contains the latest Mikron VX-10s. It is striking that the new machines are no longer green, but painted in their standard colors of gray and white. This makes the hall appear much brighter and friendlier. “We introduced a new color concept two years ago,” clarifies Mile Veljaca. The 60-year-old team leader has been with SFS intec for 14 years. “The new Mikron machines remove the cuttings very effectively. They also run very stably once you have set them up correctly,” stresses Mile Veljaca. “There’s always room for improvement, but the people from Mikron fundamen­tally do a good job.”

HAUSER – Jig grinding machine with new wheelhead

Friday, 18 November 2016 by Yongtak Ju

A major development has been achieved in the product area, HAUSER jig grinding, in Biel. A new wheelhead has been developed for the model series 45 and 55.

HAUSER jig grinding machines traditionally cater to the niche of highly accurate grinding work in tool and mold fabrication, as well as grinding production of demanding small series. The new development realized by HAUSER is aimed at a pronounced increase in productivity as well as a significant improvement in achievable processing precision. At the same time, the ability to do hard machining by grinding is supplemented with expanded possibilities for fine milling, analogous to HSC milling.

To be precise, this is achieved through a new jig wheelhead. This, with the classic characteristics of the Z axis combined with the C and U axes, represents a new, previously unknown dimension of performance and capacity on the market.

Here, a Z axis with highly dynamic oscillation capabilities was realized using linear motors. The C axis is designed with a hydrostatic bearing, which permits highly accurate planetary grinding with roundness in the sub-micron range. The new design of the U axis also has a unique, large capacity for movement.

A great deal of attention was paid to preventing the effects of thermal expansion, to ensure that the sought-after improvements in precision were actually achieved.

Overall, an unusually high degree of system rigidity, previously unknown in jig grinding, has been achieved by this new solution, providing a range of improvements, such as

  • a pronounced increase in performance capabilities.
  • new combinations of use with grinding and hard milling
  • clear improvements in precision in respect to achievable bore roundness
  • previously unimagined possibilities for automation and variations in bore grinding, mold grinding, profile grinding and every kind of conical processing

HAUSER jig grinding machines fitted with this new wheelhead are available immediately in the new model series H45 and H55. The machine frames take into account the performance increases of the new wheelhead, which is why they have been given a heavier construction. On exhibition at the AMB is the HAUSER H45-400 and corresponds, in terms of size, to the previous S45-400. A full scale machine can be viewed in Hall 8, Stand D16.

New & Efficient Fitting Polishing Technology

Saturday, 12 November 2016 by duke.lee

Issue:

When producing ASME BPE, Semiconductor or Japanese standard fittings the elbows must be polished to remove all marks and imperfections. When bending the tube there are always ‘orange peel’ marks and marks from calibrating the elbow (making it round).

Practice Today:

Today, it is polished manually or polishing using mechanical polishing machine. For manual polishing, it is usual to have a team of 40+ people manually polishing with abrasive paper.

Mechanical polishing is slower, produces a dust/metal particles during operations, and leaves residual oil. Mechanical polishing also produces less than satisfactory quality.

New Solution:

ECM Methodology developed by pECM Systems and introduced by OTRA in Korea produces far superior and consistent surface finish while reducing cost per parts significantly.

pECM Systems provides turn-key systems for the manufacture of a variety of ASME BPE stainless steel pipe fittings. The systems include machine tool, control system, electrolyte management and tooling. In addition to the tooling all process parameters are supplied so that the system can enter production immediately after installation.

Applications ‘BioPharma’ and “ultra-high purity (semiconductor)” elbows and Tee’s are produced with our technology to ensure ultimate quality and performance (below)

Benefits

  • Very fast Return on Investment (ROI)
  • No abrasive polishing material >$200k saved PER YEAR. (Based on 100,000 elbows)
  • High Production rates (One operator being able to produce > 10000 elbows per month!)
    >150 per hour 1” elbows
    > 60 per hour 1 1⁄2” elbows
  • Zero Cathode wear – 1000’s of components can be produced
  • Simple to use

Systems for manufacturing BPE components by ECM

The machine is set up in two stations. One station is for loading/unloading and another for ECM process. ECM process is carried out on each station alternatively.

The machine tool is of composite granite and stainless steel construction to ensure precision, stability and long life.

  • Designed to Machine to final dims and tolerances
