Small lot production of castings | Consistent support from pattern design to production of prototype oil filters
Are you being turned down for the cost of trial molds and setup? We provide comprehensive support from mold design to machining, and we can also prototype the AC4B-F oil filter in the shortest time possible.
Have you ever been turned down for prototyping parts with a wide variety of shapes, such as oil filters for industrial machinery, due to costs associated with wooden molds and setup? Manufacturers that outsource wooden molds often face adjustments with their subcontractors every time there is a shape change or modification during the prototyping stage, leading to increased costs and time. In prototypes where the shape is not finalized in one go, this burden of adjustment becomes particularly significant. Karmo Casting handles everything in-house, from the design and production of wooden molds and metal molds to casting, machining, and inspection. We possess five casting processes in-house: sand molds, self-hardening, alkaline phenolic, cold box, and metal molds, allowing us to respond immediately to shape changes internally. By consolidating points of contact, we can offer short lead times and low costs even for prototypes. This product is an example of an oil filter made from AC4B-F material, handled consistently from wooden mold design to machining, and responding to shape evaluations during the prototyping stage. We are offering a technical document summarizing the break-even point by manufacturing method and considerations for small lot production for free. 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 costs and lead times down even for prototypes. If mass production is confirmed, there may be further cost reductions through a review of the manufacturing method. Please start by discussing the shape and quantity with us.
