Heavy Duty Top Entry PET Preform Take out Robot

This heavy-duty Top Entry Robot by KOWEY is specially developed for PET preform applications. It comes with a standard Y-axis stroke of 1200-1500 mm, perfectly matching 300-650 T injection molding machines. Custom-built for automated top-side take-out of PET preforms, it is fully compatible with top-ejection production for all PET preform molds ranging from 1-cavity up to 144-cavity.

Built with reinforced high-strength mechanical construction, the robot is engineered for harsh operating conditions in the PET industry including multi-cavity molds, continuous mass production and heavy-load part removal. Its maximum lifting capacity exceeds 25 kg. It effectively addresses common industry pain points of heavy payload and poor stability with high-cavity preform molds. Compared with general injection-molding robots, it delivers prominent advantages in high-cavity compatibility, structural rigidity, load capacity and take-out stability. It serves as the core automation equipment for high-speed, high-volume multi-cavity PET preform injection lines.

product details

Equipment Details

PET preform take-out differs fundamentally from the handling of ordinary plastic products, mainly due to the huge variance in mold cavity quantity. PET preform molds cover a wide cavity range: 1-cavity, 8-cavity, 16-cavity, 32-cavity, 48-cavity, 64-cavity and even 144-cavity. Higher cavity counts mean more preforms per molding cycle and a sharp rise in overall take-out payload.

Conventional robots can only handle low-volume part removal. They cannot satisfy synchronous heavy-load extraction for multi-cavity preforms and fail to guarantee production stability. This robot is precisely tailored for 300-650 T injection molding machines and dedicated to top-side take-out of PET preform molds. After mold opening, the robot accurately enters the mold cavity. Using special end-of-arm tooling, it extracts all multi-cavity preforms in one single motion, retracts smoothly and completes automatic part dropping. Customized solutions are available according to mold cavity count, preform specifications and production cycle time to meet mass-production requirements for full-range PET preforms.

Equipment Advantages

Core Components

All core components are optimized for real-world production conditions for accurate application matching.

High-strength mechanical frame: the primary load-bearing foundation, specially reinforced for multi-cavity heavy-load take-out, featuring anti-deformation and wear-resistant performance for long-term stable operation.

High-precision motion system: accurately executes full-sequence motions including mold entry, top take-out, lifting, mold retraction and part dropping with smooth precise movements.

Intelligent control system: achieves accurate signal interlock between robot and injection molding machine with stable programming and fast response.

Dedicated PET end-of-arm tooling: configurable with grippers, suction cups and pneumatic circuits to realize synchronous take-out for 1-144-cavity preforms of varied layouts and weights.

Core Components

The main pain points in PET preform production centre on take-out stability under high-cavity heavy-load conditions. Customers prioritize complete multi-cavity synchronous picking, long-term stability under heavy payload, anti-vibration performance and structural durability. Traditional manual removal suffers from low efficiency, high labour intensity, poor precision, frequent preform damage and missing pick-ups.

This robot delivers fully-automated workflow: mold opening, mold entry, top take-out, lifting, mold retraction and part dropping. It replaces manual piece-by-piece handling with one-shot full-batch extraction of multi-cavity preforms. It resolves bottlenecks brought by high cavity count, heavy payload and continuous mass production, greatly boosting productivity and product yield, and supporting unmanned, stable large-scale manufacturing.
