Mold

1. Applicable Products and Processing Requirements

Mold manufacturing covers areas such as plastic molds (e.g., molds for home appliance housings), stamping molds (e.g., automotive sheet-metal molds), and die-casting molds (e.g., molds for mobile phone frames). The core requirements are: The mold cavity boasts high precision (error ≤ 0.005 mm), excellent surface finish (Ra ≤ 0.4 μm), and high machining efficiency (shortening the mold delivery cycle). Moreover, it is necessary to avoid “mold trial failures” caused by processing errors.

 

2. Dike Device Compatibility and Technical Advantages

(1) VL Series Vertical Machining Centers: Core Processing Equipment for Mold Cavities

Core compatible models VL855/VL1165 (Heavy-duty rigidity + Long stroke, suitable for molds of various sizes)

Technical Support

◦ With a spindle speed of 8,000 rpm and equipped with a “high-rigidity milling cutter,” this setup enables “high-speed milling + deep cutting” specifically for mold cavities (such as curved cavities in plastic molds). The surface finish of the cavity reaches Ra = 0.2 μm, eliminating the need for subsequent electrical discharge machining (EDM) and shortening the mold manufacturing cycle by 50%.

◦ The X/Y/Z axis travel ranges from 850×550×500 mm (VL855) to 1100×650×600 mm (VL1165), enabling the machining of molds for household appliance housings (dimensions ≤1000×500 mm) and automotive bumper molds (dimensions ≤1200×600 mm), among others.

◦ Equipped with Mold Processing Specialized Software Package It supports the “cavity automatic compensation” function. In response to mold wear—such as wear on the cutting edges of stamping dies—the software can quickly adjust machining parameters to enable “mold repair machining,” thereby extending the service life of the mold.

(2) TL Series Drilling and Tapping Machine: Machining Small Holes and Fine Details in Molds

Core compatible models TL640/TL740 (High-speed drilling and tapping + compact size adaptation, designed for mold hole positioning and thread machining)

Technical Support

◦ The spindle’s maximum speed is 24,000 rpm. For mold positioning holes (diameter ≤ 10 mm), the drilling accuracy is ±0.002 mm, and the tapping accuracy reaches Grade 6H, fully meeting the mold’s requirement for “precise positioning.”

◦ With a rapid travel speed of 60 m/min, processing efficiency is improved by 35% when machining mold details—such as plastic mold gates—thus avoiding delays in mold delivery caused by excessively long processing times for intricate details.

 

3. Customer Cases

A mold manufacturer in Zhejiang used a VL1165 vertical machining center to produce plastic molds for car door panels (material: S136 stainless steel). The cavity machining accuracy reached ±0.003 mm, and the surface finish achieved Ra = 0.2 μm. The trial mold was successfully completed on the first attempt. The mold delivery cycle has been shortened from the traditional 45 days to 25 days, and the customer order response speed has improved by 44%.
