Wear-resistant punching tools with sintered iron guide
15.06.2020 | For Punching tools applies to classic materials for Sliding guides like bronze or steel the sintered iron as a strong alternative. Thanks to its porosity, it is suitable in the die making of Meusburger very good for use as a bearings. In addition, sintered iron is wear-resistant and offers very good emergency running properties.
Sintered iron is one of the oldest products in the Powder metallurgy. During its production, metal powder with a precisely defined grain size and composition is first pressed into shape under high pressure. This creates the so-called green compact. During the subsequent sintering process, it is compacted and hardened below the melting temperature. In this process, the workpiece receives the required Strength and porosity. Finally, fine-tuning is done to ensure high dimensional accuracy of the sliding guide elements.
Punching tools with sliding guide with oil depot
The porous material sintered iron provides a significant advantage in sliding guides compared to solid sliding bearings. Oil collects in the pores so that they serve as an oil depot. The combination with the solid lubricant MoS2 in the sintered layer gives users optimal gliding properties.
The friction causes the oil to reach the sliding surface. Through the Capillary action When it comes to a standstill, it withdraws back into the sintered layer. In addition, the sliding guides made of sintered iron offer high wear resistance and very good emergency running properties. No additional lubrication is required.
Guide bushes and flat guide rails
For the bushings, 1.0503 with 50 HRC steel is used as Carrier material for the sintered layer used. An optimal diffusion zone between the steel jacket and the sintered layer guarantees an inseparable molecular connection. Guide bushes are used in the punching tool with stroke speeds of approx. 50 m / min when medium lateral forces occur.
The sockets are available with a collar (E 5122) in 20 to 63 mm diameters and for gluing (E 5152) in 12 to 40 mm diameters. The fully synthetic high-performance oil VLS 250 is suitable for relubrication.
Especially in Transfer and large tool making Flat guide rails made of steel with a sintered sliding surface are used. They offer the highest surface pressures and maximum sliding speeds. The E 6110 SIN strips can be cut to length and processed as required and are available from stock.
Mold construction and access control for control cabinet and machine
04.05.2020 | The specialist for Mold making and Locking systems Emka Fitting parts presents a new one Access control for passive outdoor cabinets. In addition, swivel handles, fasteners, turn-lock fasteners and electromechanical fasteners as well as molds and product samples from the mold making and casting portfolio are presented. They are used in control cabinet construction, electronics and mechanical engineering. The new system solutions include locking systems made of engineering plastic for Control Cabinets up to Protection class IP 65.
As a novelty, there is a locking solution for passive outdoor control cabinets or telecommunications housings or multifunction housings (MFG). Due to increasing attacks by hackers and saboteurs, the closure is of great importance as a swivel handle for the outdoor housing. To the controlled access To ensure for authorized persons, the power supply takes place via inductive power supply on demand and the release via Bluetooth-based smartphone app. The administration, in particular the definition of individual access authorizations, and the monitoring are done from a central point via management software.
Alternative to metal locking systems
The mold making specialist recently had one economical alternative Developed for metal-manufactured locking systems with multi-point locking for control cabinets. The mold making solutions in plastics technology offer efficient handling with full IP protection. A connecting rod made of fiberglass-reinforced polyamide ensures safe and stable properties.
The user operates the drive point centrally using a key plate or lever handle and thus moves the rods synchronously into the locking positions where the locking elements (pastilles) into the corresponding closure holders. This meets all the requirements for a multi-point locking system. Thanks to the modular design of the locking system, users have a selection of door locks to choose from – from the short key escutcheon to a new long key escutcheon through to the lever handle. Optionally, the lever handles can be equipped with a push button, round or profile half cylinder. All handle variants are available with or without preparation for additional padlocks.
The mold maker is known for his manufacture and manufacture of zinc die casting, aluminum die casting, stainless steel investment casting or plastic injection molding and shows his spectrum of high quality molds and selected product samples from plastic, zinc and aluminum. More than 700 employees manufacture fittings manufactured in mold construction using injection molding and other casting methods in the plants in Bosnia.
With more than 95 CNC machines in production and manufacture on a production area of around 35.000 m², Emka is one of the largest mold construction manufacturers in Europe. Emka not only manufactures products for the catalog range, but also sees itself as a bilateral development partner for its customers. All of the materials mentioned are processed into prototypes, initial samples and pilot series through to large series. Well-known OEMs such as Mercedes, Audi, Porsche and Fischer Sports have up to 900 molds and the resulting products manufactured at Emka every year.
Interactive mold making with layout editor in the mold making assistant
06.04.2020 | One of the key advantages of the webshop of Hasco, specialist in mold making, is the practice-oriented mold construction assistant. This leads to a completely configured mold for mold and tool making in just five steps. The user has the choice of six standard layouts. In addition, he can create his own individual mold structure. This opens up flexible options for designers and mold makers for the design and manufacture of injection molds or other mold construction for applications in machine and tool making or even medical technology, to name just a few examples.
The intuitiv The easy-to-use graphical interface enables quick configuration of mold structures tailored to the respective application by simply selecting and storing mold making parts.
The graphic interaction guides the user through the configuration. Plates and stripper packages can be easily added and molded parts can be quickly removed or moved from the mold base layout. Possible positions for molded parts are highlighted. This means that only sensible combinations of mold base elements are created.
Layout editor for individual mold making
Added moldings such as the double ejector package, the strip package and the stripper block offer the user further options for making their mold construction even more individual. Individual mold construction halves can also be configured with the layout editor.
After the layout has been created, the mold structure with dimensions and material specifications as well as all components and accessories can be completed in just a few steps in the mold structure assistant. The system automatically generates parts lists including cost calculations. CAD-files is available for download in various formats. This makes Hasco mold making easier than ever.
