Best way to manufacture my product

Hi everyone

i planned to make one hand holding device.The dimension of the device 90*60*40 (l*b*h). I want to manufacture this product. don,t know which manufacturing methods is cost effective.mine is start up company we don't have that much money for manufacturing.i planned to use ABS plastic.I want 20k-25k plastic casings.please give some ideas to Manufacture the product in low cast.

Thanks and regards

In my opinion, if you are going to make such a device with plastic, it would be good to consider an injection mold. It is also important to take into consideration the geometry of the device so it would fit the manufacturing technology. I can advise you on talking to some manufacturers and seeing what technologies they have and how much it would cost you.

If you are confident with the design you can look into injection molding. The tooling may cost a few thousand, but dependent on how many cavities and how many runs you are looking to get you can make them out a few types of materials. Urethane casting is quick and cheap but will only produce a small number of parts.
25,000 parts is relatively low and you should be fine with a lesser grade steel.

Here's a small breakdown:

Class 101 Mold
•Cycles: 1 million or more
•Production level: High
•Uses: Extremely high production and fast cycle times
•Investment: Class 101 molds are the highest priced and made with only the highest quality materials

Class 102 Mold
•Cycles: Not exceeding 1 million
•Production level: Medium to high
•Uses: Good for parts with abrasive materials and/or tight tolerances
•Investment: Class 102 molds are fairly high priced and made with materials of exceptional quality

Class 103 Mold
•Cycles: Not exceeding 500,000
•Production level: Medium
•Uses: A very popular mold for low to medium production parts
•Investment: Class 103 molds fall within common price ranges

Class 104 Mold
•Cycles: Not exceeding 100,000
•Production level: Low
•Uses: Good for limited-production parts with non-abrasive materials
•Investment: Class 104 molds fall within low to moderate price ranges

Class 105 Mold
•Cycles: Not exceeding 500
•Production level: Prototype only
•Uses: Good for abrasive materials and/or parts with tight tolerances
•Investment: Class 105 molds are built inexpensively to produce a very limited number of product prototypes

3D printing is an option if you believe the design may change a few more times before production quantities are seen. Would probably be more expensive in your case.

Yup, for 25,000 parts I'd say you should look into aluminum tooling for the injection molding process.
Of course the part has to be designed for injection molding as Vladimir pointed out.
Uniform wall thickness, draft angles, parting line, fills, vents, runners, fillets, ribs, no undercuts, no negative draft angles, no straight walls
I highly suggest designing it for injection molding from the start. Trying to convert a "regular" 3D model into something suitable for mass production is often a challenge.
