EPS Crusher

It is the best solution for EPS block and EPS packages waste recycle. The crusher consists of shredders and polishers. The cmbered shredders crush the EPS to symmetricl beads in low speed.

And then the polisher mill the beads to round EPS. Normally it works together with de-duster and Mixer.


EPS automatic foam machine

Automatic intermittent pressurized quantitative pre-hair machine, by the quantitative pre-press and fluidized drying drying and screening, crushing, conveying equipment and other components of the automatic cycle of foam system. Suitable for pre-foaming of expandable polystyrene (EPS) foam products, it is an indispensable machine for foam plastic products factory.

After the pre-foamed EPS foam particles, under normal pressure in the aging treatment, you can supply foam molding machine into a variety of different shapes of plastic packaging products and different specifications of foam plastic sheet. Foam products are suitable for packaging household appliances, instruments, locomotives, ships, refrigerators, refrigerators, such as thermal insulation, noise, shock the ideal material.

Large Extrusion Blowing Hollow Plastic Forming Machine

Optimization of product wall thickness is one of the major goals pursued by manufacturers of large-scale blown blow-molding hollow plastic molding machines, and is a key technology. Radial wall thickness distribution system can be in the symmetry direction of the products with greater tensile requirements of the best wall thickness control, and the extruded parison in a required section of non-circular cross-section changes, and thus improve the products Quality, surface components to improve the thickness of the internal and external radius of uniformity of great significance. At the same time, it can guarantee the quality of the premise, reduce product weight.

About EPS intermittent pre – foaming machine

Intermittent pre-dispenser (also known as quantitative pre-presses or pressurized pre-hair machine), mainly used with fully automatic packaging machine supporting, through the provision of EPS intermittent pre-foaming machine EPS intermittent pre-foam machine Uniform density without the phenomenon of caking EPS pre-material, in order to meet the production process of packaging products molding conditions. Intermittent pre-dispenser sub-vacuum intermittent pre-dispenser and general intermittent pre-feeder. With the specifications of the case is usually more continuous volume, feeding, crushing, air-drying device also requires better efficiency.

Pre-hair machine barrel in front of the set vibration level of the induction controller, foam beads can be perceived the correct degree of rise, so that the density of pre-beads more uniform, tolerance is only ± 0.3kg / m3, which is intermittent Pre-hair machine is different from the continuous one of the characteristics of pre-hair machine. Pre-release beads, the hair barrel internal temperature changes are very small, to remove the occurrence of condensation and pre-beads of agglomeration phenomenon, it can reduce the moisture content of raw materials, saving energy. + This intermittent pre – hair machine in the operation from the feeding, heating, discharge, feed to the air – drying process using automatic process control, regulation is convenient and accurate. Pre-beads from the bottom up, when reached a certain height, the signal issued by the photoelectric tube can be discharged, the action is accurate and sensitive, when the foam pressure stability, the density is almost consistent, which is the correct choice of molding conditions important.

As the automatic control equipment of the progressive support, the machine can be prepared to heat, heated to a certain temperature can easily enter the automatic pre-issued, such as failure, can be automatically displayed. Such equipment each time to join the number of beads is very accurate, the machine temperature at any time display, uniform intake, and equipped with air purging device; In addition, such equipment with air-dry, smash feeding device, but also easier to control. Feeding device generally with a ventilation filter device, powder is not easy to enter the pre-hair machine, easy to produce clogging and agglomeration. Raw material beads and lighter pre-beads, which have a lower blowing agent (longer storage time), can also achieve good results, which are advantageous for cost reduction and raw material adaptability. Particularly in view of the environmental protection requirements, some manufacturers have already implemented the use of low blowing agent content of raw materials (about 3 010), in this case the use of intermittent pre-hair machine, the production efficiency is higher.

Power System

a. In the use of pilot-operated type steam reducing and filtering system make steam pressure more stable;

b. Analog sampling,controlling central energy distribution system is according to proportional share;

c. Steam pressure,de-molding compressed air pressure and cooling vacuum pressure,flow rate can be adjusted independently;

d. Simple layout of pipes, efficient pressure management. make sure that the steam pressure and temperature inside of mould is uniform.

EPS shape molding machine

Unique machine structure:

a, High- strength frame: Further enhanced the back template and moving frame, adopt machine’s body and feet as a whole style, and make the template and machine feet integrated, greatly increased the template’s more stronger and stiffness.

c, Adopts opposite directions type tie bar for easily maintenance and wear resistance self-lubricating copper tube which solved original tie bar bushing ‘s problem and improved the lubrication effectiveness.

d, Adopt stainless steel plate for the support and back plate each contacting positions, which will reduce the wear and rust of the mold precision.

Current Situation of Domestic Molding Machine

In recent years, China’s micro-injection molding machine in the research and development has also made considerable progress. The two-stage micro-injection molding machine developed by the Hong Kong Polytechnic University’s Micro System Technology Center is capable of vacuum injection at injection speeds of up to 1000mm / s, maximum injection volume of 0.5cm3, resolution of 0.05mg, plunger diameter of 5mm, clamping force of 20kN . Injection operation is upward injection, to avoid poor exhaust, and no valve control; clamping system in the four corners are equipped with a server, can automatically adjust the clamping pressure to minimize the amount of deformation when clamping; using two sets of linear Electric motor, high-speed injection can be achieved, the accuracy level is less than mg level.

XM-E series all-electric injection machine produced by Xinpu Plastic (Shanghai) Machinery Co., Ltd. adopts all-motor drive and servo, frequency conversion and PLC control technology.
