Small lot production of castings | Consistent support from pattern design to production for industrial machine head covers.
AC2A-F
Are you struggling with the timing of mold costs and transitioning to mass production? We provide comprehensive support from mold design to machining and will mass-produce the AC2A-F head cover.
Have you ever missed the timing due to the costs of wooden molds and adjustments with outsourcing when you wanted to produce small quantities of parts like head covers for industrial machinery? Manufacturers that outsource wooden molds often have separate contacts for mold makers and casting or machining manufacturers, which leads to additional adjustment costs and time every time there is a change in shape. In small-lot production, this burden of adjustments can pressure profitability. Karmo Casting handles everything in-house, from the design and production of wooden and metal molds to casting, machining, and inspection. We have five casting processes in-house: sand molds, self-hardening, alkaline phenolic, cold box, and metal molds, allowing us to choose the optimal method based on quantity and shape. By consolidating contacts, we can achieve short lead times and low costs even for small-lot production. This product is an example of a head cover made from AC2A-F material, handled consistently from wooden mold design to machining, accommodating small-lot production. We are offering a technical document summarizing the break-even points by method and considerations for small lot production free of charge. Please download it from the link below.

Price information
If you provide us with drawings or physical samples, we will give you a free estimate. Since we handle everything in-house from mold design, we can keep mold costs and delivery times low even for small-scale production. When transitioning to mass production and increasing quantities, there may be further cost reductions through a review of the manufacturing method. Please consult us first regarding the shape and quantity.
