In today’s customer-driven design and manufacturing world, tolerances are ever-increasing as more and more functionality is being pressed into a shrinking product envelope. CAD models are now being annotated with more critical tolerances, beyond basic fit and clearance requirements, such as complex surface profiles. Since virtually all product development is now done in the CAD [...]
the mold industry lays great emphasis on efficiency. Sometime, considering the credit therein, even when business negotiation between the manufacturing and the customers is still under way, […]
The lead angle of your cutter has a dramatic effect on not only the chip that you generate, but also the cutting forces in both the axial and the radial directions. All of this can affect your overall productivity. There are many milling lead angle concepts on the market today and each is designed to [...]
The steel used for plastic molds covers a wide range, from ordinary steel to special steel. This was more obvious in the early days of plastic molds and is now becoming more advanced. Special steel has its own system. The chemical composition of mold steel is basically the same as that of alloy tool steel, [...]
When a mold designer designs a mold, he or she needs to choose correct mold steel for the mold, so the mold designer need to know some basic requirements for the performance of plastic mold steel: High rigidity and sound abrasion resistance, surface hardness of cavity should be 30—60 HRC and hardenability>55HRC, sufficient hardening depth [...]
Speed, precision and stability are the key attributes of a mold machine. With the increased accuracy demanded by sophisticated molded assemblies, particularly in the automotive supplier industry, mold shaping machine tools are breaking new ground in precision, speed and multi-axis cutting. […]
The U.S. is one of the few countries in the world still designing and building molds to inch standards when the global standard for measurement is metric. By using the inch standard our industry is out of sync with the rest of the world (except Liberia and Burma). This became clear early on in my [...]
Rust prevention for the slot or channel should be taken into account, structure of the slot and channel should be designed for the convenience of cleaning. […]
today we are going to talk about design of the guiding and position mechanism, it include […]
DFM. No, not Designed for Manufacturability, Designed for Maintainability. Every mechanical apparatus will eventually need maintenance; it’s a fact of life. Knowing this should be all the impetus needed to motivate anyone with a vested interest to give more than just passing thought to the design of injection mold tooling. The understanding that tools will [...]
