Structural change in the steel industry
The questions most people are contemplating are: to what extent will steel prices retreat in future months, and will they stay low? […]
How to do Maximum Mold Cycle Counts
The first production meeting with my new employer went something like this: “We want you to establish a PM program that is based on maximum cycle counts for all our molds.” Then, before I could launch into an explanation of how best to determine maximum cycle counts, I was hit with the follow-up: “So, how [...]
Laser system benefit moldmaker
Moldmakers are always trying to identify ways to become more efficient, reduce costs, improve quality and become more diverse. In other words, how to make more money. Talk to a molder about machine processes and they think efficiency. Talk to them about productivity and they want to find out ways to fill their shop to [...]
Sensor helps mold maker
The basis for making consistent parts for your customers is simply identifying where the physics and chemistry of plastics processing come together—inside of the mold cavity. It is in the cavity where the plastic changes from a liquid to a solid. In other words, this is where the PVT (Pressure-Volume-Temperature) properties of the plastic occur. [...]
Gas-assist analysis benefits gas-assisted injection molding
Gas-assist technology simulates the gas-assisted injection molding process, where gas is injected into the polymer melt. Gas-assist simulation was developed about 15 years ago. In the last two years, the technology has evolved dramatically with the introduction of full 3-D analysis. […]
We need Cavity pressure sensors in mold
The evolution and revolution of technology has made mold builders more sophisticated and resourceful; and, more so now than ever before—as the trying economy and outsourcing take their toll—mold builders are seeking out value-added services and competitive advantages. Sensor technology is one such area. […]
How to do an efficiently Cooling system
A common challenge faced by moldmakers is to produce acceptable parts with minimum cycle time. As cooling time accounts for most of the cycle time, reducing the cooling time of a part will considerably reduce the cycle time. However, reducing the cooling time also may result in problems, such as excessive part warpage, high part [...]
Design a right Runner system in mold
Runner sizing is a very important decision for a moldmaker. In hot runners, the moldmaker may seek to minimize the runner diameters in order to reduce melt residence time, reduce color change cycles or allow tighter pitch for drops. […]
Product Inspection helps us to check mold
While measuring the mold can be both useful and necessary, this approach poses certain problems: […]
How to do a right polishing
Ask any apprentice polisher what the most important thing about his job is and he will say “Putting on a great, high gloss polish.” Ask any veteran and he will say, “Making a profit for the shop.” […]
