模具清洁：做和不做
由：Stoner脱模解决方案专家

询问10名模塑商如何以及何时清洁他们的工具，并且您可能会收到10个不同的答案。很多时候，模具清洁取决于正在运行的部件，使用的工具类型以及模具制造商自己的过程。但是有一些通用的指导原则可以帮助保持预防性维护计划的这部分不会造成不必要的停机时间。定期清洁不仅可以提高零件质量，还可以减少生产中断。以下是一些快速指南：

制定清洁计划：

根据经验，模具在投入生产之前应进行清洁，并在进入储存之前进行清洁。无论如何，创建系统的清理时间表可以避免代价高昂的停机时间。在生产工具的同时，操作人员应该密切关注堆积物，防止它在成为问题之前进行预防。如果发生堆积，在机器附近放置一罐清洁剂可以让操作人员在现场清洁工具。

谨防权衡：

选择模具清洁剂时，快速蒸发模具清洁剂功能强大，不需要大量擦洗，并进入工具的角落和缝隙。这些清洁剂不会在部件上留下擦痕或残留痕迹。但是，不能快速起作用的清洁剂可能导致霉菌或部分污点。还有一些模塑商更喜欢使用较慢的蒸发清洁剂（即柑橘类），使其能够涂抹产品，等待让其溶解污染物，然后再擦拭工具。

关注零件质量：

一些模具清洁剂会在模具上留下残留物，如果蒸发太慢，会影响部件的质量。这可能在降低美学质量和可能的功能性能的部分留下痕迹。确保在将工具重新投入生产之前，清洁剂的清洁剂和脱脂剂已蒸发。

不要忽视防锈：

正如大多数模塑商和原始设备制造商敏锐地意识到的那样，模具的价格可能是天文数字。因此，特别是在潮湿的月份使用防锈产品是有意义的。在将工具发送到存储器之前执行此操作会在工具和元素之间产生障碍，这有助于最大限度地减少不必要的清洁。

注意树脂堆积：

在成型过程中，一些树脂可能比其他树脂更容易在工具上产生积聚。例如，尼龙以快速增长而闻名。另外，如果必须停止生产，因为部件开始显示退化树脂斑点，清洁工具是一个不错的主意。

MOLD CLEANING: DO’S AND DON’TS

By: The Stoner Molding Solutions Experts

Ask 10 molders how, and when they clean their tools, and you will probably receive 10 different answers. Much of the time, mold cleaning depends on the parts being run, the types of tools being used, and the molder's own process. But there are a few general guidelines that will help keep this part of your preventive maintenance program from causing unnecessary downtime. Regular cleaning promotes not only better part quality but also fewer interruptions to production. Here are some quick guidelines:

Develop a cleaning schedule:

As a rule of thumb, molds should be cleaned prior to being put into production, and again before going into storage. In any event, creating a systematic schedule for cleaning can prevent costly down­time. While a tool is in production, operators should keep an eye on buildup, preventing it before it becomes a problem. A can of cleaner kept near the machine allows operators to clean the tool on the spot if buildup occurs.

Beware of the trade-offs:

When choosing mold cleaners, fast evaporating mold cleaners are powerful, don't require a lot of scrubbing, and get into the nooks and crannies of the tool. These cleaners won't leave marks from scrubbing or residue on the part. However, cleaners that are not fast acting can lead to mold or part spotting. Still some molders prefer a slower evaporating cleaner (i.e., citrus­based) that allows them to apply the product, wait to let it dissolve contaminants, and then wipe down the tool later.

Keep an eye on part quality:

Some mold cleaners can leave residue on the mold that will affect part quality down the road if they evaporate too slowly. This can leave marks on the part that degrades aesthetic quality, and possibly functional performance. Make sure that Stoner Cleaners and Degreasersall of the cleaner has evaporated prior to putting a tool back into production.

Don't neglect rust proofing:

As most molders and OEMs are keenly aware, the price of molds can be astronomical. Therefore, it makes sense to apply a rust preventive product, especially during humid months. Doing this before sending a tool to storage creates a barrier between the tool and the elements, which helps to minimize unnecessary cleaning.

Watch for resin build up:

During the course of molding, some resins may produce buildup on the tool more readily than oth­ers. Nylon, for example, has a reputation for fast buildup. Also, if production must be halted be­cause parts begin to show specks of degraded resin, it is a good idea to clean the tool.
