Is it Cost Effective to Products molded in Australia rather than Overseas?

Well, in most cases Yes! Rogers Industries can offer cost effective Plastic Injection solutions based on shipping costs, quantities and quality of service. Our factory and our practices can result in a far better option for our clients, particularly with short runs and delivery service. Simply contact us and discuss your project. You'll be pleased with the results of our family Owned Australian company!

Cost v Quantity

Permanent mold casting is used primarily for medium to high production, although the process is sometimes used advantageously for low production. Cost per casting or per Kilo invariably decreases as quantity increases.

Costs for producing a 0.92lb aluminum alloy 319 casting in quantities of 100, 500, 1000 and 10,000 are itemised in the bgelow table. Costs per casting metal, degating and grinding remained the same regardless of quantity, but other unit costs gradually decreased as quantity increased. The decease in cost per casting as well as cost per KILO is approximately 30% as quantity increased from 100 to 10,000 castings.
