What is Custom Mold Making?
Custom mold making is the process of designing and manufacturing injection molds used to produce plastic parts in repeatable production cycles. These molds are built from high-grade aluminum or hardened tool steel depending on volume, complexity, and required mold life.
At XY Machining, we provide complete mold design, DFM analysis, mold flow support, precision machining, and mold assembly. Every mold is engineered to ensure dimensional accuracy, consistent part quality, and optimized cycle times for efficient injection molding production.
Mold Making Capabilities
Single Cavity Mold
Ideal for prototype tooling and low-volume production. Cost-effective and fast to manufacture while maintaining tight tolerances and reliable part quality.
Multi Cavity Mold
Designed to produce multiple identical parts in one injection cycle. Reduces unit cost and increases production efficiency for medium to high-volume manufacturing.
Stack Mold
A high-efficiency mold configuration that increases output without requiring larger machines. Best suited for high-volume production runs.
2K / Overmolding Mold
Enables two materials or colors to be molded in a single cycle. Ideal for complex components requiring enhanced functionality or material bonding.

Frequently asked questions
What materials are used for injection mold tooling?
We use aluminum for rapid tooling and hardened tool steel (such as P20, H13) for long-life production molds.
How long does it take to manufacture a custom mold?
Prototype molds can be completed in 7–10 days, while production molds typically require 2–4 weeks depending on complexity.
What is the difference between aluminum and steel molds?
Aluminum molds are faster and cost-effective for low volumes, while steel molds provide longer mold life for mass production.
Can you provide DFM analysis before mold manufacturing?
Yes. We perform DFM and mold flow review to optimize part design, gate location, and cooling efficiency before tool fabrication.
Do you support low-volume and high-volume production?
Yes. We offer rapid tooling for prototypes and hardened steel molds for high-volume injection molding production.
