We make great tools for low-volume manufacturing，Especially when quantity for hundreds and thousands of parts, we can use Aluminum and Steel material to build the mold. To shorten lead-time and reduce cost, we share the mold base and different mod cavity. The material used will depend on the type of resin, characteristics of the parts and the number of parts you required.We also make aluminum tools due the low volume. The advantage of Aluminum tool is fast modeling and most cost-effective. Aluminum is softer than steel mold, so which will be better for smaller volumes. For larger volume production, and durable mold life, we suggest to use steel mold.Steel tool is harden and more durable, which is suitable for larger volumes or injecting abrasive or corrosive plastics . But it will take longer to produce.
