In the die casting industry we rely upon our machinery to help us accomplish everything we need; this includes design software programs. There are software programs out there that can help when it comes to the die casting process. These programs help put to life what we have inside our heads with design, and can set realistic goals for us to accomplish.
When a part is sent out for quoting to die casters there are some very important issues that need to be discussed and agreed upon between the purchaser and the die caster. One of these is the finish requirement that is needed for the end product that may or may not be included on the part print or separate finish specifications for the part being quoted.
The as-cast external surface finish classifications shown here illustrate variations in production practice. Surface finish requirements should be specified for production at the most economic level.
Many designers and purchasers of aluminum die castings may not be familiar with ejector pins that leave a round seam line of flash on the die casting after it is produced from the mold.
It is very important and sometimes critical to discuss ejector pins up front in the design and launch process of a new aluminum die cast product. Omitting this discussion can lead to die revisions after the fact that could be costly to perform.
On March 21st, 2014 NADCA held a Die Cast Machine Systems Class at Premier Die Casting Company for 13 employees. The course is part of a Department of Labor Grant by New Jersey for manufacturing companies seeking to improve efficiency and productivity by employee education and skills training.
One of the most common discussions I have with prospective purchasers or designers has to do with the surface cosmetics and what the expectation is for the appearance of the gate inlets as finished. If the part is a highly cosmetic part then it is probable that the as cast/die trimmed gate will not be acceptable and will need to be sanded or removed for esthetics. The added operation will of course add cost so that must be addressed during the quote process so the customer knows what to expect long term.
