We can save money by using hot runner technology
Although a more expensive capital investment upfront, a hot runner system is a significantly more cost-efficient means to keep production costs to a minimum over the long run. […]
Using hot runner technology can have lower cycle time
The cycle time of any mold is largely influenced by the cooling cycle—how fast the resin can be sufficiently cooled so that the part can be ejected without permanent deformation. In any given mold, the areas that take longest to cool are those with the thickest wall section. […]
please realize the Importance of Runner Design and Analysis
The importance of runner analysis on design and molding seems to have been long overlooked. When many flow analyses are carried out, the focus tends to be mainly on the part and cavity. […]
What are the Common O-ring Failures?
Compression set is a phenomenon that causes most water leaks (not related to installation) in molds today. Simply put, this means that an o-ring has resided in a compressed state in the mold for so long that it has lost its ability to apply adequate force in the gland and overcome the applied water, air [...]
What is The Science of the Seal?
After an in-depth Web search and listening to numerous manufacturing reps speak in molecular detail, it is apparent that o-ring design/sealing is more complex than just a piece of rubber being squeezed between some tooling. […]
Two Types of Seals prevent water leaks
1) Static (stationary tooling) seals are o-rings placed between tooling or fittings that do not move—such as cores trapped and sealed between plates, or cavities housed in a bore with external o-rings that seal against the I.D or walls of the bore. […]
How Clean Is Clean Enough?
The type of fouling (chemical make-up and physical characteristics) or residue the molding process leaves behind on your tooling will help determine your cleaning requirements. Many resins contain stabilizers, fillers or release agents that leave residue in the form of grease, light oil, yellow waxy film or rust and white-colored dust. Some resins, [...]
How to understand mold cleaning
Cleaning is unpopular with many employees who prefer the challenge of troubleshooting or machining. Cleaning is messy, sometimes monotonous, and can be a potential health risk. There can be prejudice in a company culture that associates the job of cleaning with a lack of talent. On the flip side, […]
Systemizing mold maintenance is necessary
Systemizing mold maintenance is based on establishing consistency in repairs required (performance) and repairs performed (maintenance). Cleaning is another area where individual techniques (freelancing) greatly affect mold reliability, part quality and the tooling budget. To be cost-effective, mold cleaning must be performed: […]
Mold cleaning is very important in injection molding
Mold cleaning is a process where major maintenance bottlenecks often occur because molds are pulled faster than they can be cleaned and made production-ready. I have visited plants where molds waiting to be cleaned line hallways and toolrooms, taking up valuable bench space. Many times, in order to meet production demands, molds get reset dirty [...]
