Abstract

720,145. Injection moulding. NAAMLOOZE VENNOOTSCHAP ONDERZOEKINGSINSTITUUT RESEARCH. May 28, 1952 [June 16, 1951], No. 13591/52. Class 87 (2). Polyamides or like thermoplastic resins are injected through a passage 6 into a twopart mould 1, 2 screwed onto the injection head 5. After filling the mould and cooling, the mould is unscrewed, and then the parts 1, 2 unscrewed from each other to allow the moulded article to be removed. Spaces 4 and apertures 3 are provided to prevent the material from penetrating into the screw connection between the mould parts.
