Custom CNC Machining Mold Slider and Lifter
Custom CNC machining mold sliders and lifters are precision components in injection molding designed to enable the release of undercut or complex-shaped plastic parts from the mold. These components are custom-made to suit specific mold designs, ensuring smooth ejection and reducing mold wear and tear.
Design and Engineering:
- CAD modeling of sliders and lifters tailored to the mold geometry.
- Simulation and mold flow analysis ensure smooth movement and durability.
CNC Machining Process:
- Material Cutting: High-quality materials are cut to size.
- Precision Machining: CNC milling, turning, and grinding create the required profiles, slots, and angles.
- Heat Treatment: Enhances hardness and wear resistance.
- Finishing: Polishing or coating is applied for smoother operation and reduced friction.
Quality Inspection:
- Dimensional checks with CMM and hardness testing ensure accuracy and reliability.
Tool Steels:
- H13: High toughness and wear resistance, ideal for high-temperature molds.
- D2: High wear resistance and strength, suitable for long production runs.
- P20: Commonly used for molds requiring moderate wear resistance.
Alloy Steels:
- Used for lifters and sliders requiring enhanced toughness.
Surface Coatings:
- Nitride, titanium nitride (TiN), or hard chrome plating for wear resistance and corrosion protection.

Advantages and Challenges of CNC Machining

CNC milling and turning are highly accurate and repeatable processes. Tight tolerances between +/-0.001″ – 0.005″ can be achieved, depending on specifications. Machines can be programmed to reliably run for 24 hours, 7 days a week if necessary, so CNC milling is a good way of getting parts produced on demand.
Using standard tooling, a CNC machining service is particularly valuable for creating one-off parts, custom CNC parts, i.e., for replacing legacy components or delivering a specialized upgrade to a customer. It is also conceivable to scale single-part production to runs exceeding 10,000 units. Depending on the unit number, size, and complexity, the turnaround for CNC machined parts can be as short as one day. With shipping and delivery, deadlines can be met within a week.
One trade-off when taking advantage of the high performance of CNC machining processes is that geometric complexity comes at a cost. Simple, chunky parts are the best designs for CNC milling and turning. There will always be some design limitations due to tool access, although the degree of this effect is relative to the number of axes on the machine. In other words, the more axes used, the more complex the features can be achieved.
Another trade-off is that start-up CNC machining costs can be expensive. It is necessary to have a trained professional perform the setup, tool loading, and programming on CNC mills and lathes. Luckily this cost is fixed, so by taking advantage of the same setup for multiple parts, it becomes more economical. Saving money is also achieved by keeping part repositioning to a minimum. Machining at 5-axis and above can sometimes be more economical on multi-faceted geometries because it eliminates the need to manually reposition the part.
