Diameter gauges make 2,500 measurements per second
Sikora says that its Laser Series 6000 diameter gauges are designed for customer requirements that exceed the classic demands for quality control in the hose and
tube industry. The device makes 2,500 measure- ments per second, with high single value precision, allowing for optimum line control and reliable statistical data. Sikora offers three gauge head models for product diameters from 0.2 to 78mm. The Series 6000 can also handle transparent products. The devices include an integrated
LCD display with control panel, which provides the operator with diameter values at a glance, directly at the measuring device. At the control
CONTROL Easy-to-use extrusion controllers
West Control Solutions has introduced the PlastX family of temperature controllers for plastics and rubber extrusion. An easy-to-use menu
features pre-populated setup fi elds with default param- eters for plastic applications. This, together with the removal of unnecessary options, ensures that confi guration is straight- forward and fast to implement, says West. The controllers provide both ‘heat only’ and ‘heat/ cool’ control in the same instrument. Units can be quickly converted to process indicators, reducing the need to stock multiple products for
42
extrusion applications. PlastX controllers are
available in a compact 1/16 DIN size (48 x 48mm) and 1/8 DIN size (48 x 96mm). Standard fea- tures include process and loop alarms, with LED indicators for the band and low alarms. An LED indicator is also present during auto-tuning. The controller has one
universal input, multiple output confi gurations and optional Modbus RS485 communications.

panel the diameter nominal value can be entered and the control module activated. By way of line speed or extruder rpm, the module automati- cally controls the diameter to the specifi ed value. The high measuring rate of the diameter devices also allows the detection of lumps and neckdowns. A universal interface module is
directly integrated in the gauge heads for all connections, such as RS 485, RS 232 and Profi bus-DP, or industrial fi eld buses such as CANopen, Ethernet/IP, DeviceNet and Profi net IO. It also has an optional Wi-Fi
interface, which allows a direct connection to a smartphone or laptop for diagnostic and quality control purposes.

TUBE PRODUCTION
Flexible production of PBL tube
Breyer has adapted its Topline and Ecoline tube extrusion systems to allow fl exible, cost effective production of cosmetic tubing. Plastic barrier laminate (PBL) tubes are made from a web laminate and have a visible side seam, in produc- tion runs typically above 100,000 tubes per order. Laminate fi lm is supplied to the tube manufacturer. High speed fi lm lines, side-seam- ers and printers allow economic mass production of such fi lm but the individual design for small orders is often not economical. Breyer has developed a special solution for this, based on its experience of extrusion systems for fl at fi lm and extruded tubes. The extrusion line, with a
working width of 1600mm, 800mm, 400mm or less, allows the production of slitted fl at fi lm with a fl exible confi guration of different layers for different tube diameters and lengths. EVOH, PA, PET and COC barrier layers are all possible, says Breyer. Properties like colour and haptics, which are very important for the fi rst impression of the tube product, can be easily adapted by using different polymers such as PET, PP, PA or PE. An isolated inner layer even allows the usage of recycled material.
