醫(yī)療儀器外殼制作疾速模具技術(shù)如何？

醫(yī)療儀器外殼制作疾速模具技術(shù)如何？醫(yī)療儀器外殼我們在日常中不接觸的產(chǎn)品，自然了解的會很少，那么如果您要使用它，就從現(xiàn)在這個(gè)問題開始了解起來吧。
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.
醫(yī)療器械外殼生產(chǎn)用快速模具低壓注射成型是指將化學(xué)活性高、相對分子量低的雙組份材料按一定比例混合，然后在低壓下注射到封閉的模具中，實(shí)現(xiàn)聚合、交叉-連接、固化等化學(xué)過程反應(yīng)，并通過冷卻固化，從而產(chǎn)生產(chǎn)品的過程。
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.
產(chǎn)品材質(zhì)一般為聚氨酯樹脂，成型后具有熱固性材料的性能。產(chǎn)品的質(zhì)量與模具結(jié)構(gòu)、充填工藝、模具溫度、原料初始溫度、物料混合比和混合均勻度、固化時(shí)間等密切相關(guān)。
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.
醫(yī)療器械外殼快速模具低壓注射成型是指將聚氨酯樹脂注射到快速模具中并固化的過程。可應(yīng)用于硅膠模具、聚氨酯模具、環(huán)氧樹脂模具、ABS模具和鋁合金模具。醫(yī)療器械外殼低壓輸液成型設(shè)備主要由控制箱、定量泵、混合頭和噴嘴組成。
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.
為保證材料充分凝固，減少制品變形，一般在實(shí)現(xiàn)注塑后，需將模具移烘箱中進(jìn)行后固化。在成型過程的初期，整個(gè)反應(yīng)體系的溫度會進(jìn)一步升高，產(chǎn)生放熱現(xiàn)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.
醫(yī)療器械外殼的低壓灌注成型更需要注意工藝特點(diǎn)。例如，灌注成型工藝既有物理成型固化和熱置換工藝，也有化學(xué)聚合和交聯(lián)工藝。該過程不僅由反應(yīng)動力學(xué)和熱力學(xué)決定，而且還受物理?xiàng)l件的影響。
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.
醫(yī)療儀器外殼制作疾速模具技術(shù)如何？以上便是相關(guān)內(nèi)容點(diǎn)了，如果您需要醫(yī)療儀器外殼進(jìn)行工作或者什么，就要多多去學(xué)習(xí)的知識點(diǎn)。更多內(nèi)容就來網(wǎng)站www.hzbfpg.cn咨詢吧。
