CNC Machining / Manufacturer?


Recommended Posts

Over the last year I've been working with an industrial designer friend of mine to bring an aluminium gear knob to market.

We've been through the r&d phase and have a shape locked off ready for production. We've been very disappointed with prototype samples from two different Sydney based tool-makers - poor surface finishes, and incorrect dimensions etc.

Is anyone able to recommend a manufacture? Brisbane or Sydney based would be fine. I'd really like to get these made in Australia but so many headaches thus far...

Thanks for your help!

Sounds to me that you need to find someone who has a passion to make exactly what you want and not just for the paycheck, i know the paycheck will always be the bottom line but i am sure you will find someone who will deliver exactly what you need, it may not be a big company either it may well be a back yarder that you find through word of mouth, good luck with it Chris.

Chris, having been in this industry for nearly 35 years, as a qualified tool & die maker then as a designer (for the last 18 yrs in automotive, commercial goods, & mechanical systems), any place worth their salt should be able to machine a part like a gear knob properly with good surface finish and dimensional accurately. 

Don't take any of this the wrong way, but since you're so close to hitting the market now could be a good time to do a review.  regarding the poor quality issues so far, consider these things. 1. Is the part over complicated or difficult to machine?  In our line of business (design) people do occasionally over-design simple items, because with 3D design software you can - me included.   2. Is the correct material grade being specified?  IMO, something in the 6000 series (6061 T6), or at minimum 2011 T6 which is a bit cheaper from memory, but still anodises well.  Anything 5000 series has quite poor machinability because of it's inherent hardness and you will never achieve a half decent finish.  3. Is the price and leadtime negotiated reflected in the quality required?  Consult the Time/Cost/Quality triangle.

Have you talked to the machinist about the quality issues with the prototypes?  Ask them what needs to happen to improve the quality of the end part. 

Good luck with your item.  With the company i work for we manage projects from concept design to commercialisation.  If you want any advice or info flip me a PM. 

We need more locally made products for our cars.   I've been working on a number of items for a guy who is planning to bring to market over the next 6 - 12 months.  No gear knobs tho.

Stew, thanks very much for your input. Definitely not taking any of that the wrong way, it's good advice. The gear knob was specified in 6000 series aluminium and is of a simple / classic shape. My designer friend is having another meeting with them this week to see what can be done.

I'll share some more details via PM. 

I agree 100% when it comes to more locally made products - I really want to find a local manufacturer.
