gun drilling and ordinary drilling
So far deep hole drilling( gun drilling) has been used more and more widely in injection molds. This method requires a special machine or a deep hole drilling adaptor to another machine, […]
modern mold making
modern tooling machines for mold making generally feature multiaxial CNC controls and highly accurate positioning systems. the result is higher accuracy and greater efficiency against rejects. […]
the surface quality of a plastic part
after heat treatment, the machined inserts are finished, ground and polished to obtain a good surface quality,because the surface conditions of a cavity are, in the end, responsible for the surface quality of a plastic part and its ease of release. Defects in the surface of the cavity are reproduced to different extends depending on [...]
high-speed cutting and simultaneous five-axis milling
competition has recently developed between high-speed cutting(HSC) and simultaneous five-axis milling. HSC is characterized by high cutting speeds and high spindle rotation speeds. Steel materials with hardness values of up to 62HRC can also be machined with contemporary standard HSC millers. Sometimes, HSC machining can be carried out as a complete machining so that the [...]
a combination of milling and eroding in a mold manufacturing
for the production of injection and die-casting molds, a combination of milling and eroding may also be performed. The amount of milling should be maximized since the machining times are shorter on account of higher removal capability. However, very complex contours, filigree geometries and deep cavities can be produced by subsequent spark-erosive machining. The electrode [...]
How to ensure your design purpose
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 [...]
How to correctly repair a damaged texture in a mold
Suppose a mold needs to produce parts immediately but it has a damaged texture. This can be an everyday occurrence within a molding facility, as lifters or pins break and hit the tool surface, causing rust to develop or unacceptable texture wear to appear. These situations call for an action plan to help get that [...]
Evaluate your hot runner system design
Hot runner systems are such a common part of injection molds that hot runner suppliers must adjust component designs in order to meet increasingly stringent requirements in performance and materials, often adding to system complexity. […]
Efficiently produce a set of mold
Mold shops that recognize the potential of technology and equipment, and prioritize both accuracy and productivity will increase their competitiveness in the marketplace. The key is utilizing machines that are engineered to reduce the time-consuming elements of mold manufacturing, increase mold quality, enhance accuracy and eliminate opportunities for human error. […]
the mold industry lays great emphasis on efficiency
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, […]
