Corbas – REP international, leader in the rubber injection molding machine with the head office being located in Lyon-Corbas, France, has just concluded the acquisition of the patented HSM devulcanization technology on an exclusive right basis, as well as the devulcanization center Watson-Brown HSM-Berlin. This center is equipped with an operational devulcanization line and a test laboratory operated by a team of 6 persons.

Bruno Tabar, CEO of the REP group announces that “REP International will carry on with the development of the HSM technology, its implementation in the center of Berlin and promote a sales offer of devulcanization machines and a devulcanization service on the international market with compounders and processors“.

A resolutely promising eco-process 

Watson Brown HSM Berlin becomes so far the 7th subsidiary of the REP group, the 6 others being involved in the sales and after-sales of REP presses throughout the world. This take-over confirms REP’s readiness to extend their offer, as accentuated through their new corporate baseline “Rubber in motion”.  Aiming to work beyond the injection of rubber and devoted to the tradition of innovation at customers’ service, REP has developed a technical and commercial partnership with Watson Brown HSM the purpose of which is to devulcanize rubber production scraps and reintroduce them into the production chain.

After a series of validation tests conducted in REP’s customer plants it was established that the process is technically performing and economically efficient. That’s when REP decided after many years of collaboration to integrate Watson Brown HSM in their group.

But what is the HSM devulcanization process? 

This patented process applies to any kind of uncontaminated rubber production waste. Once the compound is devulcanized, it is reintegrated into the basic compound. This results in significant savings on both compound and waste disposal costs.

Watson Brown has developed a patent for devulcanizing cured rubber. Controlling the strain applied to the compound by the HSM machine causes the rubber to be devulcanized by preserving properties which are very close to the initial compound.

This is a 100% thermo-mechanical process without adding any further substances or chemical agents and is performed at low temperature, in order to prevent the characteristics of the devulcanized rubber from being altered.

From the devulcanization service to the series machine

REP relies on their industrialization capacities, their experience and geographical international presence to develop the commercialization of HSM machines.  The HSM structure and its components being very close to those of a press, REP has the capacities to industrialize and manufacture these machines.

With the acquisition of the intellectual property and the plant of Watson Brown in Berlin, REP is developing a devulcanization machine offer intended for compounders and rubber processors in addition to the existing devulcanization service.

HSM

What do the activities of Berlin’s center consist in?

Berlin’s devulcanization center is equipped with a laboratory to run tests on samples intended for customers who are willing to test the process based on their own compound, so as to validate the properties before running industrial HSM tests. The existing capacities grant the center the ability to service all customers who want to devulcanize and reintegrate their scraps back into production, in order to substitute them for one part of the basic compound, resulting in a drop in operating cost.

For companies interested in implementing the tests, a few kilograms of scraps will be sufficient to conduct the lab tests resulting in data on the elongation, tensile strength and rheology of the samples. After the test, the customer receives back the processed compound for assessment. It is then possible to conduct production tests to test the final parts on an industrial scale.

STAMA WILL BE AT IMTS BOOTH 8966

STAMA unveils a new concept in multi-spindle machining

 

The “2 Plus 4” principle has represented the most economical and efficient means of multi-spindle machining in manufacturing. STAMA has implemented this principle, with 2 spindles and 4 clamped workpieces, in hundreds of existing projects worldwide, resulting in radically reduced cost per part scenarios for its customers. In today’s highly competitive market, however, STAMA has recently conducted discussions with its customers concerning greater factory floor utilization and “non-productive” capacity, leading to the question, are more than 2 spindles – perhaps even 4 – for the simultaneous machining of workpieces, economically more reasonable?  This challenge has sparked an interesting development at STAMA, the 4-spindle TWIN2 concept that’s now being introduced to the world market for multi-spindle machining applications.

In answering this 2 vs. 4 question, a shop must first verify which productivity upsides will be realized by this concept.  Figure 1 below shows the productivity benefits with a 4-spindle solution on completely different manufacturing processes with different primary machining times. Contrary to the “logical” expectations, the 4-spindle solution with 4 clamped workpieces doesn’t result in double the output, compared to a 2-spindle production with 4 clamped workpieces. In the relationship between the primary machining time and the overall cycle time of the process, the actual output will usually increase by 60% to 70% by adding 2 more spindles. Individual exceptions with short time-consuming machining operations can reflect an increase of more then 80%, according to STAMA research.

While twin spindle machining needs to double the capacity of the tool magazine, the four spindle solution requires a tool magazine to handle four times as many tools. The STAMA MC 531/TWIN² is equipped with 56 tool places in the standard version, for example, with options for magazines up to 120 tools.

One major key in four spindle machining, with short tool-to-part contact times, is the load and unload sequences of the workpieces. In such cases, as long as the machine isn’t equipped with a quick automatic loading/unloading system, pendulum machining is more advisable.  This ensures parallel machining time while loading new workpieces. Time for loading and unloading can then be as long as the actual cycle time of the machine. This will also result in less time when the operator is interacting with the machine, thereby allowing the operator to run multiple stations in a work cell set-up, while keeping a constant touch time protocol on each machine.

Under these conditions, for many workpieces studied by STAMA and its customers, the “4 Plus 4” solution can result in major cost per part reduction. With over 25 years’ experience in TWIN spindle technology, the simplicity of a common Z-headstock for twin spindles from STAMA is well accepted and proven technology worldwide. The simplicity of this system is also used throughout this new TWIN² technology. Incorporating a state-of-the-art tool presetter, even single spindle manufacturing challenges with high accuracy demands can be realized with multi-spindle technology. The outstanding productivity and high workpiece quality achievable are the benchmarks by which STAMA TWIN spindle centers are known. The expansion to this 4-spindle TWIN2 machining center technology is the logical consequence of the company’s latest research and machine development strategies.

Already in full production use at a STAMA customer in one of the BRIC markets is a new four-spindle TWIN2 machining center, currently doing ABS housing manufacturing and connecting rod machining. This success for STAMA evidences the simplicity and practical application of the company’s highly productive manufacturing equipment.
