Method of and apparatus for making a box-type hollow shape |
| 摘要 |
Closed hollow thermoplastic sections are produced by extruding open part-sections from a heated die (1). The missing joining parts to close the section are formed while the material is forced through a cooled sizing section (2). To assist material flow, projections can extend from the die (1) into the sizing section (2). |
