Why Cup Molds Have High Requirements for Mold Bases?

1. Complex Cavities, High Surface Requirements: The curved surface of the cup body, handle structure, and bottom details often require high-gloss or textured finishes. This demands a stable mold base to prevent deformation.

2. Efficient and Uniform Cooling System Required: Cups are thin-walled products, requiring a well-designed cooling channel system within the mold base to ensure rapid, uniform cooling and shorten cycle times.

3. High-Volume Production Needs: As daily necessities, cups are often mass-produced. The mold base must be wear-resistant, pressure-resistant, and have a long lifespan.

4. Adaptability to Various Materials: From PP plastic cups to stainless steel insulated cups, molds for different cup materials require mold bases made from appropriate steel grades.

Changhui: Your Mold Base Solution Provider for Cup Molds

1. High-Precision Machining Ensures Cup Molding Quality

• Utilizing 35 advanced CNC machining centers ensures the flatness, parallelism, and hole position accuracy of the mold base are controlled within ±0.01mm.

• Large-scale gantry machining centers (X-axis 3500mm, Y-axis 2500mm, Z-axis 1500mm) can produce large-size mold bases for cup molds, achieving integrated molding for greater stability.

• Deep-hole drilling equipment can process water channel holes up to 1450mm deep, ensuring efficient cooling for cup molds.

2. Professional Customization Capabilities Meet Various Cup Mold Needs

• Can design and optimize mold base structures based on 2D/3D drawings of cup molds, rationally arranging systems like ejector pins, cooling channels, and venting slots.

• Supports structures like large gate mold bases, pinpoint gate mold bases, and two-color/multi-color mold bases, suitable for producing special cups like transparent cups or cups with two-color handles.

• Offers a selection of various mold steels like S50C, S136, and 718H to suit different molding conditions for ordinary plastic cups, high-temperature PC cups, stainless steel cups, etc.

3. Strict Quality Control Improves Cup Product Yield

• All steel materials are stored for 90 days before use to naturally relieve stress, followed by spectral analysis and flaw detection testing, eliminating deformation and cracks at the source.

• The entire machining process follows ISO9001 quality management, ensuring mold base precision and lifespan, helping customers increase cup product yield to over 99%.

4. Rapid Response and Reliable Delivery

• Standard cup mold base delivery within 3-7 days; large or complex structure mold bases within ≤15 days; expedited service channel is available.

• Monthly production capacity exceeds 8 million RMB, ensuring scalable delivery without delaying customer production schedules.
