What is EPS Shape Moulding Machine
An EPS shape moulding machine is a piece of equipment that helps produce expandable polystyrene. This machine helps reduce the volume of EPS, which means that it can be shipped to recycling centers more economically. It also produces a variety of shapes, such as cubes, squares, and rectangles.
An EPS shape moulding machine uses a computer-controlled machine to produce three-dimensional objects out of EPS foam. This type of foam is extremely strong and lightweight and is commonly used in the construction industry for soundproofing and insulation. CNC-controlled machines ensure consistency and accuracy in the end product.
Stainless steel steam chamber equipped on machine: Save mold frame cost, steaming from 3 sides (top & two flanks), fast fusion (especially good for package product as of better cross steaming)and rapid cooling.
Hydraulic lock system: Adopts new hydraulic-mechanical lock system;
Fast mould change, open framework design,advanced auto rod guide and fix system. Greatly reduces machine stop period, truly realizes QDCS. Mould change time 20-30min;
The design of cooling water pipe line fastens the speed of water cooling-the ring design of copper pipe inside mould cavities increases the contact surface, resulting in more efficient cooling and smooth product surface.
The process of foam molding involves using a screw to apply pressure to molten plastic. The plastic is then injected into a mold cavity. After the plastic has cooled, it is shaped. This process is cyclical and involves four steps: quantitative feeding, melt plasticizing, pressure injection, and mold closure. Once the process is completed, the product is removed from the mold, and the mold is closed again to begin the next cycle.
Quality EPP Machine, EPS Shape Moulding Machine and Auto Shape Molding Machine
THE MAIN FUNCTIONS OF THIS MACHINE
To accommodate with different sized product, this injection machine has wide ranges of mould plate, the min, dimension is around 600 × 800 mm and the max. Dimension is up to 1200 × 1400 mm. This machine is equipped with two-step hydraulic system, compressed feeding system, and central energy system, relief damper, holding-pressure water tank, condensation system, computer-controlled system, digital process control system and steam room.
THE MACHINERY STRUCTURE
This system does not require any lubricant. The hydraulic cylinder is installed in the two sides of the doom with even mould clamping force. The stainless dome can hold the heat. The mold opening and mould closing are managed by the computerized system which can ensure the best feeding accuracy. The mould ejection motion is controlled by the ejection system to provide the best quality of precision product during the ejection process.
THE LAYOUT OF THIS MACHINE
This machine is designed as a three-dimension open space. This open-space design will fasten the mold changing process and operators can change the mold from the front, back and two sides of this machine. Also, this machine can be placed directly on the ground without setting any platform. To secure the safety of the operators, this machine is equipped with safety door and security system.
MOLD SYSTEM
This mold is made in three-piece plate format. More energy can be reserved without doom and therefore, the mold plate can be highly utilized. The leader pins and spray gun are installed within the mold moving plates to ensure the safety of operation. To reduce the idol time, this system provides faster mould installation and changing system.
HYDRAULIC SYSTEM
Two-step hydraulic system provides two speeds (fast and slow) options for mold-closing and mould- opening. Also, the processing time is reduced.
CENTRAL ENERGY SYSTEM
This machine has one full set of central energy system which is produced by our company All steam and air which are needed during the injection process are controlled by the central energy system valve. This system will provide even air intake and can be adjusted easier. This low-pressure steam system is designed with enlarged pipes and valves which can provide best working condition.
THE PRESSURE RELIEF DAMPER
The adjustment of energy pressure is very important. Under higher steam pressure, the production time will be prolonged and consume more energy. However, the final product might be deformed and the surface appearance of the product might be affected when the pressure is too low. The relief damper functions when releasing mold and heating up the mold. The compressed air is used for filling and this damper will reduce the consumption of energy and provide high quality product.
THE HOLDING-PRESSURE WATER TANK
The machinery is equipped with one set of holding pressure water hank which has two different entries for cooling water and condensate.
VACUUM SYSTEM
The vacuum system is equipped with the Liquid Ring Vacuum pump and condenser which provides more efficient vacuity. Without any extra drying step, we can speed up the injection under this vacuum system. The mold ejection is easy to be completed and also save the more energy.
COMPUTER CONTROLLED SYSTEM
This injection machine is equipped with computer- controlled system which has the functions of editor and expansion. every step of operation is precisely under controlled by this computer system error detection and indications are displayed on the screen Every model is installed with this compute system which displays the procedures, time setting and priorities pressure control valve will set the pressure.
