Injection Molding Machines - Plastic Gears

AI Thread Summary
A cost analysis for an injection molding machine and mold for producing nylon plastic gears is being sought, specifically for a part with a 2 cm diameter and 20 teeth, aiming for an output of approximately 600,000 gears annually. The discussion includes inquiries about the type of injection molding machine needed and the estimated costs for the machine and a steel or aluminum mold with one cavity. While one participant suggests the Electramax machine may be suitable, they note that insufficient details have been provided to make a definitive recommendation. The conversation emphasizes the need for more specific information to accurately assess equipment requirements and costs. Overall, a thorough evaluation of machine specifications and mold design is essential for successful production planning.

Hello,

I need some help with the general very basic cost analysis of an injection molding machine and a mold for a particular part (Plastic Gear).

For example, a Gear made out of Nylon plastic resin. The gear dimensions are roughly 2 cm diameter (20 teeth). Something like the black one here - http://www.gears-manufacturers.com/gifs/plastic-gears.jpg" . I need to make let’s say approx. 600,000 gears per year.

What kind of injection molding machine would be needed? How much would the machine cost? How much would the mold cost for the above given dimensions (Assume the mold is made out of Steel or Aluminum with 1 cavity)? Can someone give me a price range or some advice on how to go about it?

Out of these which one do you think will be able to do the job? http://www.romi.com.br/ip_linhas_maquinas.0.html?&L=2" .

Thank you.

Just on the surface of it, the Electramax seems best-suited for your purposes. In reality, though, you haven't provided anywhere near enough information for a decision to be made (and I'm not qualified to make one anyway; my plastic moulding experience was non-injection of polyurethane).
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
