医疗仪器外壳制作疾速模具技术如何？医疗仪器外壳我们在日常中不接触的产品，自然了解的会很少，那么如果您要使用它，就从现在这个问题开始了解起来吧。
How about rapid mold making technology of medical instrument shell? Medical instrument shell we do not contact in daily products, natural understanding will be very few, so if you want to use it, from now on this problem to understand it.
医疗器械外壳生产用快速模具低压注射成型是指将化学活性高、相对分子量低的双组份材料按一定比例混合，然后在低压下注射到封闭的模具中，实现聚合、交叉-连接、固化等化学过程反应，并通过冷却固化，从而产生产品的过程。
Medical devices use the rapid mould low pressure injection molding shell production refers to the high chemical activity, low relative molecular weight of a two-component material mixed in certain proportion, then injected into the closed mold under low pressure, polymerization and chemical reaction process, such as cross - links, curing and cooling solidification, the process of producing products.
产品材质一般为聚氨酯树脂，成型后具有热固性材料的性能。产品的质量与模具结构、充填工艺、模具温度、原料初始温度、物料混合比和混合均匀度、固化时间等密切相关。
The material of the product is generally polyurethane resin, which has the properties of thermosetting material after molding. The quality of the product is closely related to mold structure, filling process, mold temperature, initial temperature of raw materials, material mixing ratio and uniformity, curing time and so on.
医疗器械外壳快速模具低压注射成型是指将聚氨酯树脂注射到快速模具中并固化的过程。可应用于硅胶模具、聚氨酯模具、环氧树脂模具、ABS模具和铝合金模具。医疗器械外壳低压输液成型设备主要由控制箱、定量泵、混合头和喷嘴组成。
Rapid mold low pressure injection molding for medical device shell is the process of injecting polyurethane resin into rapid mold and curing. It can be used in silicone mold, polyurethane mold, epoxy mold, ABS mold and aluminum alloy mold. The low-pressure infusion molding equipment for medical device housing is mainly composed of a control box, a quantitative pump, a mixing head and a nozzle.
为保证材料充分凝固，减少制品变形，一般在实现注塑后，需将模具移烘箱中进行后固化。在成型过程的初期，整个反应体系的温度会进一步升高，产生放热现象。
In order to ensure that the material is fully solidified and reduce the deformation of products, it is generally necessary to move the mold to the oven for post-solidification after injection molding. At the beginning of the forming process, the temperature of the whole reaction system will be further increased, resulting in exothermic phenomenon.
医疗器械外壳的低压灌注成型更需要注意工艺特点。例如，灌注成型工艺既有物理成型固化和热置换工艺，也有化学聚合和交联工艺。该过程不仅由反应动力学和热力学决定，而且还受物理条件的影响。
The low pressure perfusion molding of medical instrument shell needs to pay more attention to the technological characteristics. For example, perfusion molding processes include physical solidification and thermal replacement, as well as chemical polymerization and cross-linking. This process is not only determined by kinetics and thermodynamics, but also affected by physical conditions.
