Germany's 4Jet Group has introduced a handheld laser for cleaning tools and molds. Compared with conventional cleaning methods such as dry ice blasting or grinding, the dry process is quiet and dust-free, and does not use any chemicals.

The system is compact in design, light in overall weight, and can be operated intuitively via a touch screen.

4Jet Group claims that the cost of laser-based systems has advantages over professional sandblasting or dry ice systems. The company added that it is basically maintenance-free and does not require any consumables. 

If the system replaces energy-intensive processes, the energy efficiency and low CO2 footprint of the system may make users eligible for government rebates.

4Jet also provides hand-held laser systems for high-speed cleaning, and fully automatic laser systems for stationary applications.

Earlier this month, 4Jet opened an office in Atlanta, which will eventually become the company's headquarters in North America and Mexico. A laser cleaning demonstration center is planned for the site.

The mechanical stroke regulator (MSR) developed by Oerlikon HRSflow for hydraulically actuated valve gate systems is designed to facilitate the individual preset of the open position of the pins in the hot runner system. By adjusting the screw, the user can specify a separate oil volume, and then the valve gate system uses that volume to bring the needle to the specified position. In this way, the pressure drop of each nozzle can be set independently, and the pressure distribution in the packaging stage can be controlled. 

The new MSR can be directly installed on all the company's existing hydraulic cylinder series equipped with electric valves. The installation only takes about 10 minutes and can be completed without disassembling the mold. No need to modify the existing hot runner cuts.

The first batch of users confirmed the ability of the new MSR to balance melt flow in cascade molding, thereby avoiding surface defects. According to Oerlikon HRSflow, a large number of tests have also proved its successful use in household molds. 

The new mold splitting cart designed by Processing Technologies International LLC (PTi) brings flexibility, ease of use and operator safety to extrusion mold maintenance and maintenance operations. uCams carts are available in three configurations for cleaning, inspecting or repairing single, double or triple manifold molds. The heavy-duty frame structure on the casters provides mobility and accessibility, so maintenance can be carried out in a safe and convenient environment and height for the operator.   

The uCams mold divider is adapted to mold widths between 1,000 and 2,000 mm (39 and 79 inches) through adjustable trunnion brackets. PTi says this versatility is a huge benefit for plastic processors using different mold widths, because it eliminates the need for multiple carts or trunnions of specific widths. 

The single-hand wheel mechanism allows one person to perform the parting procedure. After manually rotating the wheel, within a few seconds, the mold is divided into individual components, which can then be rotated 360 degrees to fully approach the mold surface. 

The onboard toolbox further improves workflow efficiency with all necessary equipment and tools readily available.

The Carousel system significantly simplifies product sampling in the production process, and the Multisize Sample Carousel developed by Dinnissen goes one step further, enabling samples of different sizes to be collected in an automated process. The processor can also determine the order and frequency of sample sizes.

The Multisize Sample Carousel can collect up to 20 samples of different shapes without operator intervention. The turntable can be seamlessly integrated into new and existing production lines, keeping downtime to a minimum, and Dinnissen technicians will work with customers to design an efficient sampling process according to their specific situation.

These systems are designed to be easily accessible to achieve rapid and thorough cleaning, which is particularly important to ensure compliance with food safety and product quality requirements.

Proco Machinery has upgraded the flame processor for the automatic bottle manufacturing system with multiple enhancements, including automatic auto-ignition control that only ignites and controls the flame when needed. According to the company, this can save a lot of energy and directly reduce operating costs. 

The system is equipped with built-in safety features, including electronic sensors, to monitor the flow of containers in and out of the fire area. If a blockage occurs, the flame will automatically stop and an alarm will be issued to remind the operator. 

The combustion system is carefully designed to provide maximum flame control and efficiency, providing the best surface quality for decoration or label applications.  

Models can be used to handle containers as large as 45 gallon drums. The burner can be adjusted in height and width. The angle can be adjusted for irregular or conical containers. 

Proco offers a dual burner model for rectangular containers, flame treatment of both sides of the bottle, and a four-burner system for processing round bottles. The four-burner device has a built-in container turnover mechanism, so all sides of the bottle are fully processed.  

The standard model is equipped with a stainless steel conveyor with adjustable guide rails and variable speed motors. The height of the unit can be easily adjusted via the handwheel. The burner assembly, combustion control, and conveyor belt are all mounted on a common support structure, so they all move together when adjusting the height to prevent pipes or wires from being stretched or squeezed. 

The new mobile bulk bag unloader with Flexicon mobile flexible screw conveyor can discharge bulk solid materials dust-free and transport them to downstream processing equipment or storage containers. Bulk-Out BFF series unloaders are mounted on locking casters and have four adjustable extension rods that can accommodate bulk bags with a height of 36 to 84 inches (914 to 2,134 mm). The detachable bag frame with Z-Clip strap bracket allows the bulk bag to be fixed on the ground and then put it into the receiving cup on the unloader frame with a forklift. The Spout-Lock clamp ring on the top of the pneumatic telescopic tube secures the clean side of the bag mouth to the clean side of the device. When the bag is emptied and stretched, the bag will be under continuous downward tension, thereby promoting flow and evacuation.

The Flow-Flexer bag activator raises and lowers the relative bottom of the bag into a steep V shape at a certain time interval. The Pop-Top extension device installed on the top elongates the entire bag and promotes complete discharge without manual intervention. 

The discharge shell of the mobile flexible screw conveyor is supported by a mast fixed on the mobile discharge rack, allowing free-flowing and non-free-flowing bulk materials to be transported to multiple destinations.

The flexible screw is the only moving part that contacts the material. It is driven by a motor and goes beyond the material discharge point to prevent the material from contacting the seal.

The system is made of carbon steel with durable industrial coating and stainless steel material contact surface, or it is made of all stainless steel that meets industrial, food, dairy or pharmaceutical standards.
