METHOD OF FORMING BLANKS FOR THE SOLID-PHASE FORMING OF THERMOPLASTIC ARTICLES |
摘要 |
<p>An improved, essentially scrap-free, solid-phase process for making thermoplastic articles directly from a resinous material powder. The process can be particularly advantageous in forming large parts by compressing the powder into briquettes, sintering the briquettes, repressing the briquettes when in a heated condition into blanks and then shaping the blanks into a preform which can then be thermoformed into a product such as a container, assuming the blank itself is not the desired end product. Alternatively, sintering can take place after repressing with preheating of the briquette prior to the repressing step. 27,818-F -?-</p> |
