The transformation of raw materials into glass takes place around 2400°F (1315°C); the glass emits enough heat to appear almost white hot. The glass is then left to “fine out” (allowing the bubbles to rise out of the mass), and then the working temperature is reduced in the furnace to around 2000°F (1100°C). [...]
Glassblowing is a glassforming technique that involves inflating the molten glass into a bubble, or parison, with the aid of the blowpipe, or blow tube. A person who blows glass is called a glassblower, glassmith, or gaffer. […]
Mold-blowing was an alternate glassblowing method that came after the invention of free-blowing during the first part of the second quarter of the first century A.D. A glob of molten glass is placed on the end of the blowpipe which is then inflated into a wooden or metal carved mold. In this way, the shape [...]
According to first-rate mold company’s president , Steven, consumer products are all about shelf appeal and function, and moldmakers must respond to this demand with creativity and innovation in order to remain competitive. […]
Due to the intensive machining practices that must be performed on mold bases, if machining time and costs can be reduced, significant savings can be realized. […]
An integrated approach made it simpler, more cost-effective and time-efficient for First-rate mold company. Having one supplier coordinate the mold base and hot half freed up a lot of time for Sullivan to focus on the cavities and cores of the mold. The designs of the hot half were formatted and attached to the mold [...]
Designing a product for high production tooling involves considerations that must be closely evaluated: gating location, part ejection, wall thickness, material flow characteristics, cycle time, hot runner feasibility and assembly at high rates. […]
Managing heat and delivering resin at a consistent temperature is the role of the nozzle. There are several features that one should consider before making a nozzle choice. It is important to maintain consistent heat due to the temperature processing window unique to today’s highly engineered resins. Engineered resins have an ideal target temperature that [...]
Not surprisingly, foreign competition has posed a bit of a challenge to First-rate mold company . To combat this, Steven president of First-rate mold company, explains the company launched an “aggressive” equipment acquisition program. We try to be proactive in selecting the equipment for the departments, which will have the biggest impact on production. [...]
