Mold Frame

In bottle manufacturing, the mold frame is a key support structure. It holds the actual bottle mold securely in place inside the high-speed blow molding machine. During operation, it ensures precise alignment and stability for the mold, which is critical for making consistent, high-quality bottles. This is especially important on hot-fill lines where equipment faces extra stress. The size 397.0 x 192.8 x 310.7 mm is a common specification we produce for these applications.

Main Material: We use a high-grade imported aluminum alloy. This provides a strong yet lightweight foundation.

Surface Protection: The frame receives a special proprietary coating. This layer significantly improves its resistance to daily wear and tear.

Manufacturing Precision: Production involves precise CNC machining. We work to tight tolerances that ensure a perfect fit for your specific mold setup. We can provide exact tolerance figures based on your requirements.

Primary Job: Its function is to act as a rigid mounting platform. It correctly positions the mold halves and absorbs the operational forces during the blowing cycle.

Handles Tough Conditions: Its design accounts for the heat of hot-fill processes and the constant motion of high-speed machines.

Quality Material: Starting with superior aluminum means the frame has good structural integrity and thermal properties from the beginning.

Extra-Long Life: The protective coating fights against abrasion and corrosion, helping the frame last longer and require less maintenance.

Accuracy is Key: Precise machining guarantees that your mold fits perfectly every time. This accuracy is essential for consistent bottle shape and trouble-free machine operation.

Field-Tested Design: This type of frame is used successfully in many PET bottle plants. Its reliability is proven in actual production.

Practical Knowledge: We design parts based on an understanding of how they are used on the factory floor.

Custom-Built Parts: Our standard process is to make items to order. Send us your drawings or a sample, and we will manufacture the frame you need. We also produce standard sizes like the one mentioned.

Wide Compatibility: We have deep experience with frames for Krones-compatible lines. However, our workshop can also manufacture frames suitable for other brands of rotary blow molding equipment.

Direct from the Factory: Purchasing directly from us, the manufacturer, offers better value and allows for clear, direct communication about your project.

Industry: Manufacturing of PET bottles for drinks, juices, sauces, and similar liquids.

Equipment Type: High-speed rotary blow molding machines.

Place in Line: Installed at the blow molding station, where it serves as the critical base for holding the production mold. It is a necessary component for hot-fill applications.
