Hot Runner Pinpoint Cooling Mould | 1x64 Multi-Cavity PET Preform Mold | High

Product Specification

This industrial-grade multi-cavity injection mold is specifically engineered for the high-volume production of small, intricate plastic components, most likely PET preforms for the beverage industry or precision medical/electronic parts. The mold features a dense "1x64" cavity layout, enabling manufacturers to produce 64 identical parts simultaneously in a single injection cycle. This high-cavity configuration is the pinnacle of efficiency for mass production, drastically reducing per-unit manufacturing costs and maximizing output on the factory floor.

Alternative Names & Working Principle:​

Commonly referred to as a "preform mold," "multi-cavity hot runner mold," or "valve gate mold," this equipment operates on advanced plastic injection molding principles. Thermoplastic materials, such as PET (Polyethylene Terephthalate) or PP (Polypropylene), are melted in an injection machine and forced under high pressure through a hot runner system into the 64 individual cavities. The visible red cylindrical components on top are valve gate units, which provide precise control over the flow of molten plastic, ensuring each cavity fills uniformly and minimizes pressure loss. Once the plastic cools and solidifies, the mold opens along its guide pillars, and the ejector pins (visible on the rear plate) push the finished parts out.

Material & Craftsmanship:​

The mold body is constructed from high-strength alloy steel, such as P20 or 718H, offering excellent durability and dimensional stability under high temperatures and pressures. The surfaces of the cavities and cores are machined to a high-gloss finish, which is critical for producing transparent PET preforms with optical clarity, free from blemishes or scratches. The overall silver-metallic color reflects the industrial-grade quality, while the precise alignment of the numerous cooling channels and electrical connectors highlights the mold's sophisticated engineering.

Performance & Features:

· Extreme Production Efficiency:​ With 64 cavities arranged in a compact grid, the mold significantly reduces cycle times and increases daily output compared to molds with fewer cavities.

· Valve Gate Technology:​ The integrated valve gates ensure a clean, automatic separation of the runner system from the parts, eliminating manual trimming and reducing waste.

· Advanced Thermal Management:​ The mold features a complex network of cooling channels (evident from the drilled holes) that maintain optimal temperatures during the molding process, preventing warping and ensuring fast, uniform cooling for each cavity.

· High-Precision Ejection:​ The rear view reveals a robust ejector system with multiple red and blue hydraulic or pneumatic fittings, indicating a reliable mechanism for the smooth removal of finished parts.

Applications:​

Ideal for bottling plants and packaging manufacturers, this mold is essential for producing the preforms that are later blown into water, soda, or juice bottles. Its design also suits the production of other high-precision, small-scale plastic components requiring high clarity and consistency.
