熱板焊(han)(han)接機(ji)主要(yao)通過(guo)一個(ge)由溫度控(kong)制的(de)加熱板來焊(han)(han)接塑料件。
焊接時，加熱板置于兩個塑料件之間，當工件緊貼住加熱板時，塑料開始熔化。在一段預先設置好的加熱時間過去之后，工件表面的塑料將達到一定的熔化程度，此時工件向兩邊分開，加熱板移開，隨后兩片工件并合在一起，當達到一定的焊接時間和焊接深度之后，整個焊接過程完成。
1、熱(re)板(ban)焊接機根據熱(re)板(ban)裝置可分(fen)為垂直式或平行式。
2、熱(re)板焊接根據模具可分為橫向和臥(wo)向。即橫向式(shi)熱(re)板焊接機和臥(wo)式(shi)熱(re)板焊接機。
3、熱板焊(han)(han)接機(ji)體積(ji)因焊(han)(han)接件的大小(xiao)而定，根據設備的大小(xiao)驅(qu)動(dong)(dong)方式(shi)可選擇(ze)氣(qi)動(dong)(dong)、液壓驅(qu)動(dong)(dong)或伺(si)服馬達驅(qu)動(dong)(dong)。即氣(qi)壓式(shi)熱板焊(han)(han)接機(ji)和油壓式(shi)熱板焊(han)(han)接機(ji)。
4、根(gen)據焊(han)接程序(xu)要求，可選擇半(ban)自動或全自動模式(shi)。設(she)備保(bao)持良好穩定性(xing)(xing)，能保(bao)證(zheng)一致的(de)(de)焊(han)接效果及工件加工后高度(du)的(de)(de)準(zhun)確性(xing)(xing)，焊(han)接溫度(du)，加熱(re)時間，冷卻時間，加熱(re)深(shen)度(du)，熔接深(shen)度(du)壓力，轉(zhuan)接時間等(deng)參數均(jun)可調。其(qi)它選擇性(xing)(xing)的(de)(de)焊(han)接參數也可調，水(shui)平熱(re)板設(she)計的(de)(de)設(she)備，熱(re)板可作(zuo)90°旋轉(zhuan)以便清(qing)潔
