Mechanical Structure:

High-Strength Frame & Platens: 

Utilizes high-quality steel and high-rigidity design to ensure a stable clamping system, minimal deformation, and precise, uniform clamping force, meeting the high-pressure molding demands of thermosetting plastics.

Optimized Clamping Mechanism: 

Often employs robust and reliable double-toggle or direct-pressure clamping mechanisms. Features smooth, precise mold opening/closing actions, high speed, and excellent repeatability, extending mold life.

Precision Guide System: 

The moving platen is equipped with large-diameter, high-precision guide pillars and bushings, ensuring smooth operation, strong resistance to eccentric loads, and enhanced molding stability.

Robust Injection Unit Mounting: 

The Injection unit is securely mounted to the machine base, minimizing vibration during injection and ensuring shot accuracy.

Optimized for Thermosets: 

Circuit design specifically addresses the high processing temperatures (typically >150°C) of thermosetting plastics. Utilizes high-temperature resistant seals and hydraulic oil to ensure long-term system reliability.

Precise Temperature Control: 

Integrated high-efficiency oil cooling system (e.g., high-capacity cooler) precisely maintains hydraulic oil temperature within the optimal operating range (typically 45-55°C). Prevents oil overheating, which can cause viscosity drop, seal failure, and system instability.

Efficient & Stable Pumps & Valves: 

Employs low-noise, high-response servo pumps or variable displacement pump systems, paired with precision servo or proportional valves. Enables fast, smooth, and precise motion control with significant energy savings. Optimized valve blocks minimize internal resistance and ensure fast response.

Optimized Heat Source Isolation: 

Hydraulic lines are routed away from high-temperature barrel and mold areas whenever possible, or equipped with insulation to minimize external heat influence on oil temperature.

Cleanliness Control: 

Equipped with high-performance filtration systems to maintain hydraulic oil cleanliness, extending component life and ensuring system response accuracy.

Screw Design: 

Dedicated Thermosetting Screw: 

Features screws specifically designed for the characteristics of thermosetting plastics (e.g., Phenolic, BMC, DAP). Typically characterized by a lower compression ratio (approx. 1.0:1 - 1.8:1) and shallower flight depths to minimize excessive shear heating that could cause premature curing (during plasticizing).

Optimized Shear & Mixing: 

Screw tip design (e.g., pointed tip, non-return valve) and placement of shear elements are optimized to provide controlled and uniform shear mixing, ensuring homogeneous plasticization without scorching.

Wear & Corrosion Resistance: 

Screws and barrel liners often undergo special surface treatments (e.g., nitriding, hard chrome plating) or are made from wear-resistant alloys (e.g., bi-metallic) to withstand abrasion from thermosetting compounds and their fillers, as well as corrosive decomposition byproducts.

Precise Temperature Control: 

Barrel features multiple, precisely controlled temperature zones (typically 4-6 or more). Utilizes efficient heater bands and cooling (air or water) devices to ensure the material receives an accurate and stable temperature profile within the barrel, preventing localized overheating/curing or insufficient plasticization.

Good Cleanability: 

Screw and barrel design facilitates easy disassembly and cleaning of cured material residue, reducing downtime.

Fomtec Bakelite Molding Machines, through their robust and stable mechanical structure, high-temperature resistant and precisely temperature-controlled hydraulic system, and thermoset-optimized screw design, collectively ensure high efficiency, stability, precision, reliability, long service life, and superior molding quality when processing thermosetting plastics. They are particularly well-suited for demanding applications in electrical, appliance, automotive components, and more.

Low Pressure & Slow Speed Molding: 

Thermoset injection molding typically employs relatively lower injection pressure and slower injection speeds to avoid excessive shear heating and scorching. Fengtie machines' hydraulic and control systems are well-suited to meet these process requirements.

Applicable Materials: 

This design is particularly suitable for thermosetting plastics like Phenolic (PF), Amino (MF/UF), Unsaturated Polyester (BMC/SMC/DMC), Epoxy (EP), DAP, etc.
