5 Advantages of Machined Parts over Molded Parts

Dichtomatik ExpressWhether you are a multi-billion dollar equipment manufacturer, a nationwide industrial distributor, or a small hydraulic cylinder repair shop, these 5 advantages will help make you understand why machined fluid power seals, backup rings and O-rings from a computerized numerical control (CNC) operation are sometimes a better solution than traditional molded parts.

  1. Zero Quantity Minimums – Let’s face it, unless you need hundreds to thousands of pieces of a particular item, quantity minimums suck. Why should anyone be forced to pay for 500 piston seals when they only need 50? Answer: they shouldn’t. Instead, a CNC machining operation allows customers to choose from a buffet of different sizes and types of seals without racking up an unnecessarily large bill. Additionally, you won’t suffer from unnecessary costs to create a new production tool like you would from traditionally molded parts.
  1. Prototyping – Everyone likes to try new things, be innovative and improve equipment performance. However, can these ideas become a reality when the cost is so high for parts? Once again, a company should not be restricted to buying a hundred pieces, when they only need a few different sizes of each item. The flexibility of purchasing a low volume of fluid power seals and O-rings will provide your company the ability to seek new developments. So rather than let your innovative ideas float away along with wasted money and inventory, look to machined parts to help cultivate those ideas into a reality.
  1. Quick Turn-around Time – If you need parts, and you need them quick, CNC machining is your best friend. While it may depend on the particular type of part and material needed, the average time to create one seal or O-ring is approximately 15 to 20 minutes. With that kind of quick production you can have potentially 50 parts in nearly any size or style delivered to your front step in less than 24 hours. Whether you work on a manufacturing line or in a hydraulic equipment repair shop, CNC machined seals will help get your or your customer’s operation up and running again quickly.
  1. Sealing TechnologiesCustomizable – One size does not fit all, especially when it comes to sealing technologies. Hydraulic systems require several different types of seals such as piston seals, rod seals or wear rings, and may require multiple profiles depending on its complexity. A CNC machining operation can help overcome this obstacle by allowing customers to customize seals to their end application. In addition, the CNC machine can read two-dimensional prints or drawings of parts which quickens the process even further. If you do not have a print or drawing, gland dimensions can be quickly converted to produce a functional seal.
  1. High Quality – One of the best characteristics of a CNC machine operation is that it creates durable seals and O-rings made to sustain the toughest applications. In nearly every application where a molded seal or O-ring is used, a CNC machined part could take its place. So don’t think that because it’s essential to business success that you should wait weeks to receive a molded part rather than order a machined part. Chances are the machined part will perform just as well as its molded counterpart.
