Collapsible cores for the plastics industry<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The market demands ever more complex plastic parts at lower prices. The collapsible core is the ideal solution for demoulding injection-moulded parts with threads, undercuts or claws as cost-effectively as possible. Undercuts of 12% can be demolded without any problems – in special cases, 17% to 20% undercuts are possible with a 2-stage system<\/strong> (product innovation)<\/strong><\/a>. <\/p>

Each drop-in core is manufactured specifically to your customer requirements. The most diverse contours can be realized. Diameters from 8 mm to 240 mm are possible, with a contour length of up to 130 mm. The overall length of the drop-in core is determined individually. <\/p>

We deliver the collapsible core with the complete contour to you ready for installation – so that your complex plastic part can meet the high quality requirements at low prices.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
