DKM 72-Cavity High-Speed Preform Line

11s Cycle Breaks Efficiency Limits – Uniform Wall Thickness, Compatible with High-Speed Blow Molding

The 38th China International Plastics and Rubber Industry Exhibition (CHINAPLAS 2026) will be held at the National Exhibition and Convention Center (Hongqiao), Shanghai, from April 21 to 24, 2026. DKM will present its latest 72-cavity preform production line at booths 5.1C71 & 5.1C75, featuring live, fully automated high-efficiency production from raw material to finished preform.

This preform line continues to innovate in cycle time, energy efficiency, and product consistency, providing customers with a mature, reliable high-cavity preform turnkey solution. The finished preforms are widely used in water, beverage, cooking oil, and daily chemical packaging.

PET Preform Mold

  1. The preform mold for this line is supplied by SINOMOULD, a specialized mold supplier, with the following core advantages6.Mold Main Material
    ●Main body made of high-performance tool steel – high strength, good wear resistance, ensuring stable long-term production.
    ●Key hot runner components use high-grade hot work steel – excellent thermal fatigue resistance, suitable for continuous high-speed operation.
    Hot Runner System
    ●Valve gate hot runner – clean gate, no stringing, stable neck dimensions.
    ●Uniform heating with temperature deviation within ±1°C, ensuring consistent cavity-to-cavity weight.
    Cooling System
    ●Independent high-efficiency cooling channel per cavity, significantly reducing cooling time.
    ●Optimized cooling layout – uniform mold surface temperature, preforms removed without deformation.
    Manufacturing Strength
    With years of preform mold manufacturing experience, the mold supplier combines high-precision machining centers and inspection equipment – ensuring qualified delivery within 2weeks of 48&72cavity mold

Preform Line Injection Molding Machine: DKM-450PET III High-Speed Machine

DKM provides the 450PET III series high-speed machine for this preform line, with an injection speed of 200 mm/s and 20-30% energy savings for the whole machine.

Heating System
●Infrared heating bands (EXXSON brand): heating conversion rate up to 99.8%, 30-85% energy savings compared to conventional bands, more precise temperature control, uniform preform wall thickness, and reduced heat emission in the workshop.
Control System
●Standard electric accumulator enables simultaneous plasticizing during mold opening, significantly improving cycle time.
●Servo motor drive increases screw speed by 20-50%, better plasticizing efficiency with low energy consumption.
●Standard 15-inch KEBA PLD with the latest control software, to make the 11-second cycle a reality.
Oil Pump & Hydraulic System
●Upgraded oil pump provides higher flow, achieving 200 mm/s injection speed – fast filling, ideal for thin-wall preform rapid molding.
●Rexroth dual proportional valves for hydraulic control: response time <0.1 sec, fast injection response, precise positioning.
●Mold opening/closing position repeatability error ≤0.2 mm, ensuring stable preform removal by robot.

We Invite You to See It Live at CHINAPLAS 2026 – Booths 5.1C71 & 5.1C75

At CHINAPLAS 2026, DKM will demonstrate the entire 72-cavity preform production process live – from injection molding and cooling to removal and conveying – giving you a firsthand look at the true efficiency of an 11-second cycle.
Welcome to visit booths 5.1C71 & 5.1C75 to discuss high-efficiency molding technologies and energy-saving solutions for the preform packaging field with our technical team. If you would like a quotation in advance, discuss a specific project, or schedule a meeting at the show, please contact your DKM account manager.
