How to treat Welding Mark of Injection Molding
The most influential factor for welding intensity is the temperature during the confluence of melt. In actual engineering practice, commonly-used methods for treating welding mark include: […]
Welding Mark of Injection Molding
The thread mark formed at the front confluence of two or more melt flows in the cavity is called welding mark or welding line. Usually, apart from low mechanical intensity, such defect as depression and aberration may also occur at places where welding mark appears. […]
Welders should consider for mold and die steels
With every weld repair comes challenges with EDM recast layers, platings, coatings, steel types and filler rod choices. we’ll break down these problems and recommend repair procedures that welders should consider for mold and die steels. […]
How to secure an effective mold repair procedure
In most welding shops, there is a certain procedure for handling a mold from when it arrives for repair to when it is ready for a customer. At my company, it is a seven-step process that may require adjustments depending on whether we are using micro-TIG or laser welding. […]
How to select properly sized alignment components
Traditionally, designers have relied on a general “feel” or “rule of thumb” to decide which alignment locks to insert within a mold, considering sizes and mounting preference. That’s adequate, right? Maybe not. Selecting an alignment lock based only on gut feel could result in an undersized selection and, down the line, can result in costly [...]
Injection molding Solutions for insufficient filling
1 Use plastics with low viscosity and sound fluidity or adjust prescription of plastics and reduce viscosity of melt; 2 Improve barrel temperature, increase injection pressure, raise melt temperature to reduce erection degree, and improve plastication quality; 3 Improve mold temperature and uniformity thereof, raise nozzle temperature and properly set cold-slug well ; 4 Increase [...]
Injection molding problem– Cannot Be Sufficiently Filled
The plastic melt condenses and solidifies before it can smoothly fill in the cavity part far away from the gate or that with thin section, the cavity therefore is insufficiently filled and the shape and structure of the molded products are incomplete, which is intrinsically due to the low fluidity and poor filling capacity of [...]
How to prolong cutting tool life
The benefits of prioritizing expected tool life over price when choosing metalcutting tools are clear, especially in the precision-focused and deadline-driven moldmaking industry. Reputedly, economical tools often provide abbreviated and unpredictable life that results in poor tolerance control and leads to expensive rework. […]
Discuss the use of beryllium copper alloys in plastic injection industry
Copper beryllium alloys are heavily used worldwide in the plastic industry in the manufacture of injection mold components that are then used to make containers from different types of plastic resins. It is estimated that 50 percent of the plastic injection industry uses this material for this purpose. […]
Modern software can help Wire EDM during taper cutting
Software can help compensate for excessive erosion during taper cutting with wire EDM. Wall straightness or angle accuracy often present a challenge to the machine operator when he or she is attempting to wire EDM taper angles. Several factors within the EDM process affect angle accuracy. These include, but are not limited to, temperature, machine [...]
