将裁切后的软质材质及硬质材质进行红外加热的步骤包括：将裁切后的板材203(即软质材质及硬质材质)放置到镂空托盘204上，将镂空托盘204滑至红外烤箱200中；红外线灯管201加热板材，温度感应器202检测温度是否达标。红外加热的升温速度为5℃/s-20℃/s，加热效率高，能够使软质材质及硬质材质表面的温度快速升温到板材203所使用的树脂的玻璃转化温度与熔融温度之间，此时板材203变软，但不会有熔融的液体滴下。
在步骤30中，将红外加热后的软质材质及硬质材质置入模具中，其中为了防止红外加热后的软质材质及硬质材质热量损失，需快速将软质材质及硬质材质置入模具中，例如，可采取机械手臂抓取、置放的方式。
所述模具包括热压模具，所述热压模具上根据需要可以设有咬花，由此在成型时可使对应的机构件产品100外观部101具有咬花，所述咬花可为仿皮革纹或木纹等形状，所述模具上的咬花通过镭雕雕刻进行，模拟度高。
所述热压模具上设有抽真空结构，例如抽真空孔，所述抽真空结构与抽真空设备连接，在成型机构件产品100时抽真空，达到产品上无气泡的功效。
在步骤40中，模具合模，并对软质材质及硬质材质进行热压成型。其中，步骤40可以包括：模具合模到保留0.5mm-2mm的间隙，此时模具型腔将软质材质及硬质材质固定，模具快速加热，软质材质及硬质材质通过模具的对流与 辐射加热；软质材质及硬质材质升温后，模具进行缓慢加热，直至加热到软化温度，模具完全合模，进行热压成型，并控制模具温度及热压持续1秒-3秒的时间，以使机构件产品100均匀成型。
其中，热压模具加热的方式包括电加热、蒸汽加热或电磁感应加热，本实施例中可以采用蒸汽加热的方式。
在步骤50中，模具开模，取出机构件产品100。可选地，在模具设置的管路中通入冷水，对模具进行快速降温，此时模具仍处于合模状态，机构件产品100也快速得到降温，机构件产品100定型后，模具开模，取出成型后的机构件产品100。
在步骤60中，对成型后的机构件产品100进行后加工，以达到更优的机构件产品100外观效果。
上述成型方法通过对软质材质及硬质材质叠层后采用红外加热的方式加热，提高了加热效率，加热后放入热压模具中压合成所需要的立体形状，硬质材质成型为机构件产品100的结构部102，软质材质成型为机构件产品100的外观部101。由此，可以得到兼具可折叠效果及一体化外观的机构件产品100，且还能克服传统热压成型制品厚薄不均，应力分布不均，及有褶皱等缺陷，得到均匀高质的一体化机构件产品100，另外成型周期短，周期小于1分钟，提高了量产效率，制程简单易行，适宜工业化生产。
