lost foam casting applications

Electric steam automatic pre-foaming machine

Pre-foaming machine is one of the very important equipment for lost foam casting white area. At present, there are mainly two kinds of electric steam heating pre-hair machine and steam heating pre-hair machine, are intermittent work, the control system uses the most advanced PLC technology, pre-hair beads uniform. It is composed of automatic electronic weighing (optional) or quantitative feeding system, foaming machine pressurized foaming barrel and computer control system, discharging system and fluidized buffer bed. Electric steam pre-generator can be a key to open, automatic feeding, fool type operation, unattended. Name Unit Parameters Barrel body Dimensions mm φ450*800 Volume m³ 0.13 Steam Entrance mm DN25 Working pressure MPa 0.03~0.1 Compressed air Entrance mm DN25 Working pressure MPa 0.4~0.8 Installed power 9.2KW Production efficiency ≤25Kg/h Floor Area 3.5*2*3m ★Product Structure 1. Pre-generator host 2. Electromagnetic heating system 3. Fluidized bed 4. Automatic quantitative system (optional automatic weighing system) 5. Feeding system (fan * 3) ★Main functions and advantages A key to start, fully automatic operation, EPS, STMMA (copolymer) universal. Pre-beads uniform size, low moisture content, no dead particles, basically no caking. Easy installation, small footprint. Automatic control: automatic feeding, automatic weighing, advance, automatic unloading and a series of steps such as parametric control, automatic operation, and reserved in the system manual operation procedures, convenient for small batch trial production and maintenance of human settings, the two methods of operation conversion flexible and convenient.

Hydraulic forming machine

The molding machine is a special equipment for the molding of the white area of the lost vanfollowing mold. It takes expandable polystyrene (EPS) or copolymer as raw material. After the raw material is foamed, dried and matured, the EPS and copolymer beads are automatically fed into the mold by the machine, and then steam is passed into the mold to heat and form the mold. After cooling and shaping, the foam plastic products are automatically separated from the mold by compressed gas.

Steam automatic pre-foaming machine

Pure steam pregenerator can set stirring time and steam time in time according to process requirements. The barrel body adopts closed constant pressure foaming, which has high thermal efficiency, saves steam, and saves energy by 50% compared with continuous pregenerator. The density is stable and the particles are uniform. It can also be applied to the pre-foaming of EPS, EPMMA and STMMA copolymerization.
