AWI springs into action at CASMI event Round, flat and profile wire manufacturer Alloy Wire International (AWI) used its presence at SpringWorld 2022 (CASMI) in Illinois, USA, in October to launch its new Inconel alloy 686, a single-phase, austenitic alloy that delivers resistance to the general and stress corrosion cracking that can occur in aggressive liquids and gases.

to support firms who supply products into automotive, aerospace, medical, nuclear and the resurgent oil and gas markets. “They require material that can work in all types of demanding applications from intense heat and sub-zero temperatures to highly corrosive environments. This is why we are so pleased to be launching Inconel alloy 686 after months of trials and testing.” The wire is available in sizes ranging from 0.025 to 5mm (0.001" to 0.197"), and can be made to customer specification within three weeks. AlloyWire International www.alloywire.com The MGF+ 100B is suited to injection moulding applications, and has no centre hopper, so that all materials must run through the feeders. This model includes a material collection bin with a level sensor that maintains material level by activating the dispensing of materials on demand. Processors can also now choose the latest version of Maguire’s MVF volumetric feeder. Designed for simple volumetric dosing of colour concentrate and/or additive material, it utilises a digital push-button set-point control and a stepper motor to provide consistent let down ratio without the use of load cells. Conversion kits are available for upgrade to full gravimetric capability.

The wire is expected to be used with in components destined for corrosive environments, in industries that require materials to perform under extreme en gineering conditions without premature failure. Areas of application will include springs, wire forms and fasteners used in chemical

and petrochemical processing, oil and gas extraction, acid processing, waste man agement and in marine environments. Stephen Olley from AWI commented, “Spring makers had a fundamental role in the Covid-19 response, and we continue

troller. The centre hopper dispenses the virgin material. For each unique feeder, the dispensed material is measured pre cisely and accurately to maintain the correct percentage, all controlled by one touchscreen controller. The newMaguireMGF+ 100L incorporates up to four different auger feeders, and includes a virgin hopper that is on a pair of load cells so that the material within this hopper is also weighed and controlled by the same controller. All materials are 100 per cent weighed, and the additive components are ratioed to the primary component, regardless of changing throughput. This option is best used for extrusion applications. The MGF+ 100X takes the process con trol a step further by including an extru

Maguire has introduced a new feeder line that can be configured to accommodate various processing requirements. The models allow for up to four different sizes of auger feeder, all located on one mounting frame and using a single common touchscreen control. The company is also introducing a volumetric feeder (MVF) option. The new feeder models provide flexibility for injection moulding, extrusion, blow moulding and extrusion control applications. Maguire’s standard MGF line provides robust hardware integrated with soft- ware to provide consistent control and accuracy that is easy to use. The standard Maguire gravimetric feeder (offered in three auger sizes – 3 / 8 ", 1 / 2 " and 1") has historically included analogue or touchscreen control, along with different mounting frame options and high temp configurations. The series offers twin load cell technology with a dosing accuracy of ± 0.2 per cent. The new MGF+ gravimetric feeding units give processors more flexibility and increased performance for all types of moulding and extrusion processes, and can be retrofitted in the field with current Maguire feeder equipment. The MGF+ line incorporates the standard gravimetric feeder options. Having up to four different sizes of auger feeder on one mounting frame allows the flexibility to dispense multiple additives/ materials within one frame and one con

sion control package, where the extruder drive control is man aged with the same touchscreen controller as the hopper and the feeders. This model, used exclu sively for extrusion applications, streamlines the entire process and includes the centre loss-in weight (LIW) hopper along with up to four auger feeders. The LIW controller monitors the actual throughput of the line. The target throughput is set on the controller, and when the operator switches to automatic mode, the controller will adjust the extruder drive to maintain target weight per hour and/or weight per length.
