Top Entry PET Preform Take out Robot
Equipment Details
The core challenge in PET preform production lies not in single-piece molding, but in consistent and stable picking of mass-produced preforms from multi-cavity molds. Multi-cavity mold production imposes strict requirements on robot picking speed, positioning accuracy, gripper stability and continuous-running capability. Delayed robot movements will directly extend injection molding cycle time; malfunctions such as missed picking, dropped preforms, preform jams and mold collisions will severely compromise product quality and equipment safety. This top-entry PET preform robot follows the standardized workflow: injection molding, mold opening, top-entry preform picking, fast mold retraction, cooling & conveying, and finished-part collection. It accurately solves key issues including delayed picking and unstable operation in high-speed production, ensuring efficient and continuous production-line operation.
Equipment Advantages
Custom-built for PET preform production, this robot features four core strengths: multi-cavity compatibility, high precision & efficiency, stable low-consumption performance and easy maintenance.
Its dedicated top-entry structure fits the layout of PET multi-cavity molds. Preform picking is performed utilizing overhead space, adapting to various mold layouts and injection-molding machine spatial conditions.
Fitted with a special multi-cavity preform picking mechanism, it picks preforms from multiple cavities simultaneously and removes an entire panel of preforms in one go, eliminating the inefficient single-piece picking mode.
Built with lightweight yet high-rigidity construction, it balances running speed and structural strength. It perfectly matches the injection molding machine cycle without redundant pauses or idle waiting.
The heavy-duty frame supports round-the-clock continuous production with precise positioning and smooth motion. It effectively avoids dropped preforms and mold collisions. It can seamlessly interface with cooling, conveying and collection systems to replace manual handling and sorting, lowering labor reliance and production costs. It features simple operation and convenient maintenance with outstanding long-term operational reliability.
Equipment Parameters
Top Entry PET Preform Take-out Robot-Light Configured for light weight, broad compatibility and high stability. Primarily compatible with 250T-550T PET-dedicated injection molding machines. Standard 1300 mm long Y-axis stroke fully meets stroke requirements for standard preform molds. It easily handles the weight of full-panel multi-cavity preforms in one pick, suiting production conditions for molds with high cavity counts and heavy-weight preforms. Full high-speed servo drive delivers smooth, compact motions throughout preform picking, mold access/retraction and homing, precisely matching the short-cycle, high-rhythm production mode of the PET industry. High repeat positioning accuracy guarantees consistent mold-entry positions for the multi-cavity picking plate, eliminating offset, mold collision and missed preform issues at the hardware level. It supports seamless signal communication with mainstream-brand injection molding machines and adapts to varied mold-opening-and-closing timings. Parameters can be flexibly adjusted according to mold cavity quantity, preform dimensions, production speed and production-line layout, delivering excellent versatility and adaptability.

Applicable Products
This KOWEY robot covers a wide range of applications, supporting multi-cavity injection-molded PET preforms for mineral water, beverages, carbonated drinks, edible oil, fruit juice, dairy products, large-capacity PET bottles and cosmetic transparent PET packaging bottles. It is highly suitable for core scenarios: multi-cavity molds, high-speed injection molding, round-the-clock continuous production and automatic cooling & conveying. Specific configurations can be customized based on injection-molding machine tonnage, mold cavity count, preform size & weight, and production cycle. Core hardware includes mechanical transmission, drive, control and pneumatic systems, together with PET-specialized preform picking plates, clamping units, rotating mechanisms and line-connecting assemblies. Real-time signal exchange between the control system and injection molding machine enables fully automatic completion of preform picking and subsequent processes with zero manual intervention.
Core Accessories
Custom‑designed for high‑speed continuous PET production. The transmission components feature excellent wear resistance and fatigue resistance, while the drive assemblies deliver fast response. Special preform‑gripping accessories are compatible with multi‑cavity molds of varying cavity counts. The clamping force is uniformly adjustable to effectively preserve the appearance of bottle preforms. The full set of accessories delivers outstanding stability and low wear, greatly extending the continuous‑operation cycle of equipment and reducing subsequent maintenance costs.
Application Site & Customer Feedback
After deployment on production floors, the robot thoroughly transforms traditional PET preform manufacturing. It resolves long-standing pain points: manual on-site preform picking, heavy workload for bulk preform handling, tedious manual transport and labor shortages during peak seasons. The equipment automatically executes cyclic operations: mold-opening top-entry picking, full-panel preform removal, fast retraction and automatic conveying & cooling, requiring no constant manual attendance. Production lines are upgraded from the intermittent “injection molding + manual pick-and-place” mode to fully-automatic continuous production. Production continuity and output stability are greatly improved, labor costs and product defect rates are reduced, and mass-order production becomes more reliable.
