3From small pins for wristwatches to large pins for use in transmissions, meter-long pins, Castec manufactures pins by leveraging the comprehensive knowledge of its experts.Castec is able to adeptly machine steel, whose dimensions change when subjected to heat, and ensure dimensional accuracy for a range of surface treatments.Core pinsCore Pins (Core Pins for Die Casting) / Cooling HolesCompletely straight precision stop holes down to 1.5 mm in diameterCastec has the technology to machine completely straight ne holes up to 280mm in depth at φ1.5mm and up to 440mm in depth at φ2 mm (up to 600mm at φ3, up to 700mm at φ4, and 750mm at φ5) in lathed metal.Furthermore, we are able oer products in a wide range of shapes thanks to the technology we possess for machining to a thickness of just 0.7mm between the hole and the exterior circumference and for post-machining processing of hole interior surfaces. As well as stop holes we can also deal with requirements for through holes, eccentric holes, and holes in angular shapes.Spru core/BushCastec’s Plant No.1 boasts a dedicated line for machining spools.This spool line has the capacity to manufacture 50 sprue core/bush sets per month.Dedicated machining lines for fully made-to-order manufacturingManufacturable range: φ300 x L300(Please feel free to inquire regarding diameters greater than this)We can also create a variety of cooling structures and runners.(Guaranteed with a pressure leak test at 0.6MPa)Castec’s Technology Services Department has the equipment and facilites to analyze the cause of problems such as galling, fracturing, and cracking in core pins, inserts and spools, and to make suggestions for remedies.By borrowing products that are no longer in use from our customers and providing solutions from a range of perspectives, we can extend the lifespan of products and thus help to improve customers’ productivity.Technical ServiceSERVICE 02SERVICE 01
