disposable PP food grade cutlery plastic fork knife spoon making machine

This is an injection molding machine designed to produce disposable PP (food-grade) cutlery such as forks, knives and spoons. With the appropriate mold it can also produce similarly sized single‑use food utensils.

It is a hydraulic plastic injection molding machine with a precision hydraulic synchronous template adjusting system and a high‑precision machine computer control for stable, repeatable molding.

It is optimized for food‑grade polypropylene (PP). Other thermoplastics may be processed if compatible with the screw/barrel and mold design, but food contact applications should use FDA/EU‑compliant resins and validated molds.

Key specs include 2000 kN clamping force, tie‑bar spacing 515 × 465 mm, mold thickness range 180–560 mm, ejection stroke 150 mm, ejection force 77 kN, maximum system pressure 16 MPa, oil pump motor 18.5 kW, heater power 13 kW, overall dimensions ~5000 × 1600 × 2000 mm and approximate weight 5.6 tons. Screw speed range is 0–200 rpm.

Cycle time depends on part geometry, wall thickness, mold design and cooling. Typical cycle times for disposable cutlery commonly range from several seconds to around 20 seconds. Final production rate should be calculated from validated cycle time with your specific mold and process.

Molds must fit within the tie‑bar spacing and mold thickness limits (180–560 mm). For food utensils use polished stainless steels or appropriate food‑contact tooling materials, proper cooling channels, and consider hot runner systems or multi‑cavity layouts to meet production targets.

The machine is designed to mold food‑grade PP parts, but compliance depends on using certified food‑grade resin, hygienic mold materials and cleaning procedures. Final regulatory compliance (FDA, EU, etc.) is the customer's responsibility and requires validation of materials and processes.

It includes a large screen, high‑precision machine computer system (PLC/HMI) for process control, parameter setting and monitoring, making operation and recipe management straightforward.

Design highlights include a modularized energy conservation oil‑way system, balanced transfer oil cylinders, optimized electric system and efficient lubrication to reduce energy waste. Actual consumption depends on cycle, heaters and runtimes.

Routine maintenance includes daily cleaning of the mold and barrels, checking oil levels and filters (magnetic filter and bypass strainer), greasing lubrication points, monitoring wear parts (screw, barrel, sliding blocks), and scheduled hydraulic oil and filter changes per the supplier manual.

The machine includes hydraulic synchronous template control, robust clamping, emergency stop and interlocks. Standard guarding and safety devices should be installed per local regulations; additional safety customization can be provided by the supplier.

Yes — you can change molds to produce different shapes and cavity counts. Discuss required production rate, cavity count, mold layout and optional equipment (e.g., hot runners, chillers, automation) with the supplier to size and configure the system appropriately.

Most suppliers provide installation and commissioning, onsite or remote start‑up assistance, operator and maintenance training, plus technical support. Exact services and warranty terms vary—confirm scope and costs with the vendor before purchase.

Wear parts such as screws, barrels, seals, heaters, filters and hydraulic components are typically available from the manufacturer or authorized distributors. It is recommended to stock critical spares to minimize downtime.

Contact the supplier with required specifications (part design, cavity count, production rate, local voltage and optional equipment). Lead time depends on configuration and mold manufacturing but commonly ranges from several weeks to a few months; get a formal quote for accurate timing.
