We focus on new developments in major machines that may be of interest to North American processors.
To get this all in, we won\'t repeat everything covered in last month\'s \"first highlight\" sampling (p. 15)
In the preview of our two showsSept. \'92, p. 51 and Oct. \'92, p. 35).
Some news about materials and additives appeared elsewhere in this issue;
Some appeared in the preview of last month and September, and more appeared in subsequent issues.
Next month, we will close the mechanical report with new developments in RIM and polyurethane equipment.
K\'92 is full of news for injection molding.
A particularly active area is small machines that introduce new models and focus on special molding applications such as multi-component molding and metal or ceramic powder injection. Gas-
At the booth of many machine suppliers, the auxiliary injection also plays the leading role, showing the application of thermoplastic and thermosolid.
Other highlights to note are

Two new machine models, 270 V and 370 V, launched the V series at 33 U speedS. tons.
Both are equipped with the new Sealogica control system.
The size of the C Series has also increased.

The clamp insert molder of Arburg is based on the full circle M design.
The injection device is mounted vertically on a removable pressure plate or can be mounted horizontally on the parting line.
The full circle rotary table is equipped with a fixture of 44 to 143 tons.
One area that is becoming more and more important for Arburg may be metal --or ceramic-

Several improvements to boy 50 (50-ton)
The machine is at hand.
The bar gap has increased from 12 to 13. 2 in.
, And expanded the fixture safety guard to increase the available space around the mold.
The injection unit has been redesigned to replace two horizontal pairs of hydraulic pistons with a rotating piston system, which the boy 80 has proven.
It is said that it can reduce the quality of movement during injection.
The injection force is not transferred to the screw drive bearing, and the injection profile control is said to have been significantly improved.
Boy 50 also includes an improved variable --
Displacement pump with hydraulic volume and pressure adjustment.
It is reported that in the new version, it is not necessary to adjust the pressure difference of the pump, thus improving the efficiency of the pump.
The pressure is monitored by the sensor in the pressure system, and the throughput is measured by the position sensor on the pump piston.
Among the other improvements, Boy 80 (80-ton)
The model increases the bar distance from 14. to 16 in.
In addition, the MIP ronic Plus controller includes a new interface for a product weighing scale with tolerance monitoring that can be integrated with a separate device for rejectionspec parts.

Two aspects of mold design are also important.

, So that different materials will not stick together when curing, and will not prevent the free movement of the components.
The system adopts a horizontal injection unit that is vertical and two parallel, and one injection unit is moved for each mold.
The injection device injects three stations of the rotating mold at the same time, generating parts of three parts at a time.
At the first station, the switch blades were produced by molding process;
Then inject the moving rod of PP onto the blade;
Finally, the shell of the PP completes the part.
The whole cycle is about 30 seconds.

Benefits of self-reporting
The clamping system makes it easier to change the mold, make it easier to contact the mold, and save floor space, energy consumption and tool costs. A space-
Hemscheidt GmbH shows the design of the economical Hydraulic Mechanical fixture from the former East Germany.
The clamping device can be used on machines of 550 to 3300 tons, with four short irons that retract in each cycle.
The end of each post bar is specially configured to engage the locking mechanism on a fixed template.
There are four separate clamping cylinders on the fixing table plate, and then pull the iron bars to generate clamping force.
This design is used on many larger Japanese and Italian machines, first appearing on smaller models of Klockner and Fahr Bucher as well as Hemscheidt.
Hemscheidt claims 40% less floor space than conventional clamping machines (
\"The smallest 500-

Although Hemscheidt has not yet been actively listed in the United StatesS.
According to a company spokesman, the company is considering setting up an office here.
Staubli introduces a manual bayonet system for quick clamping of injection molds (Duncan, S. C. ).
The system consists of two bayonet locking plates and a removable lever, each with a centering ring.
After quickly positioning the mold between the stick of the machine, the template is closed, and it is said that the locator and the centering environmental protection certificate have accurate positioning.
Fix the mold by simply manually locking the centering ring.

They are based on proportional voltage power output and PID2 control, ensuring that the constant power supply of the heater is not affected by the line voltage and limiting over-impulse.
There are two models to choose from: 9152 (two-zone, 15-amp), and 9034 (four-zone, 3-amp).
The optional minipanel allows global trimming of all areas with one command before switching to operating conditions, programmable startup conditions for timing loops, and the ability to store setup programs that automatically set all controllers of the mold.

Husky\'s runner nozzle is also new.
It allows edge gating of single or multiple parts with engineering resin by eliminating insulator bubbles found in most edges
Gate system, which may be the source of resin degradation.
In order to eliminate any dead angle between the nozzle and the cavity wall, when the heated internal material of the nozzle expands and forces the sealing ring to lean against the gate wall, a seal is created.
There is a small gap between the sealing ring and the gate-
Well walls that provide insulation. The seal-

The spring assembly provides pre-load, ensuring that a seal occurs between the nozzle housing and the manifold even before any heat is added.
When the system reaches the operating temperature and the manifold expands, the spring expands and ensures full sealing.
Another key feature of the super nozzles is their \"clampless\" slidingOn the warm wind
These eliminate bulky fixtures and catch the heater due to thermal expansion.
Instead of the usual two belts, this can produce two hot spots, one single slip
