Anatomy of Quality


 

 

 

A quality mold must start with quality steel. If you know what kind of steel you want, just let us know and we'll be happy to make your tool from it. If you're not sure, give us a call and we'll recomend a steel based on the type of plastic you're molding and the number of parts the tool will be required to produce.

This is an area where many mold builders try to save a few dollars. Not only will they skimp on the quality of the steel, but they'll also produce a tool that doesn't have enough steel in critical areas. This can lead to very costly problems for you as a molder. It only costs a few more dollars to design the tool with the needed strength. Don't let a mold builder talk you into skimping in this area.

 

Got water?  A mold builder can produce you a perfect seal off, that makes perfect parts, but if the tool doesn't have enough water, you'll never make a dime. Why invest thousands of dollars in a tool only to have your cycle times ruined by poor mold cooling. You can plainly see the water in the A side of the tool to the right. The B side has plenty of water as well. Note the quick disconect fittings. They are recessed into the mold so that it can set on any surface, and allow for quick mold set ups when it's time to run the tool.

 

 

 

 

 

Support is often overlooked. Injection molds operate under large amounts of pressure. Even the best and thickest plates of steel cannot withstand those pressures without moving. If your mold is moving under injection pressures, your part will not be right. You'll have problems with flash, premature wear, and even damage to your expensive investment.

 

 

 

Don't limit yourself. Note the location of the knock outs on this tool. This mold can be run in any orientation, and on nearly any machine. This allows you more flexability. I've seen many molds built with just one set of knock out holes. Sure, it's easier for the mold maker, but how many different machines do you have in your facility? How will that limit you when you buy new equipment?

 

This tool was fitted with replaceable "hockey puck" style knock out adapters at the customer's request. This allows them to easily replace any threaded knock out rods that may become damaged. Other styles of quick disconect or replaceable knock outs can be used at your request.

 

 

 

 

3D parting lines. Gone are the days of endless hand fitting parting lines. Today's tools require state of the art programing software coupled with machine tools and craftmen that know how to make them perform. Having the ability to "machine to net" increases mold quality, decreases lead time, and improves reliability. We keep a 3D solid model on file for each mold that we build. Allowing for faster, less expensive repairs and engineering changes. We also have the ability to reverse engineer complex parting lines and part shapes to facilitate quick repairs on tools where prints or models are not available.
