If customer has been engaged in the plastic granulating industry and purchased our plastic recycling plant machines, HaoSu will send a technician for on-site installation and technical guidance. This enables customers to quickly operate our plastic granulating system for manufacturing.
If customers have been committed in plastic granulating industry for many years, HaoSu provides installation instructions or video, FAQ or online guidance to clients.
Of course, we can still provide on-site installation service if necessary.
If clients buy our plastic processing lines, HaoSu gives a set of non-standard wearing spare parts free of charge. As for high value spare parts, HaoSu offers those at a most favorable price.
If the key spare parts of plastic recycling line experience quality problems, HaoSu will arrange an after-sales service team to provide solutions and solve the after-sales problems. If the problem is occurring in a small component, they can be directly replaced by the customer, but we will quickly deliver the parts and provide online guidance if necessary.
HaoSu provides plastic recycling plant reforming service if customers want to improve the current yield or quality of plastic granule. For example, if customers want to reduce labor cost, we can offer automatic design for some machines in the recycling line to reduce partial labor and cost.
If your plastic recycling line is aging and needs to replace some machinery, HaoSu is able to change all the aging equipment to upgrade your plastic recycling line.
|The recycled plastics contain many impurities||Strengthen the cleaning and screening processes, increase mesh numbers or layers of filter screen|
|The feeding bin experiences localized overheating, causing carbonization of the materials.||Reduce the extruding temperature and increase mesh numbers or layers of filter screen|
|The plastic extruder machine features strong local shearing force, resulting in material carbonization.||Reduce the extruding speed and increase mesh numbers or layers of filter screen|
|The pressure of die-head is too high and the reflux material is too great, causing material carbonization.||Increase the temperature of the die-head; Change the filter screen and reduce its mesh numbers.|
|The equipment is aging and the adhesion inner the cylinder increases.||Change equipment or spare parts|
|The accumulated material in the discharge hole is carbonized and discharged.||Clean the gas exhaust hole regularly.|
|Discharge hole is not smooth and the accumulated material is carbonized and discharged.||Clean regularly or change spare parts.|
|The screw thread is damaged and the material in the dead corner is carbonized.||Replace or repair the screw.|
|Gas exhaust is blocked, leading to materials carbonization.||Clean the exhaust hole and keep it clear.|
|Insufficient extrusion amount||Raise the rotating speed of screw, feeding speed or change the filter screen.|
|The high temperature of the die-head leads to low material viscosity.||Properly reduce the temperature of die head.|
|Poor plasticizing causes plastic agglomerates||Increase the extruding temperature or speed to promote full plasticizing.|
|Mixing materials are different in characteristics.||Adjust the temperature or speed based on actual conditions.|
|Gas exhaust is blocked and the plastic strips have pores.||Ensure smooth exhaust and reduce the extruding temperature properly.|
|High moisture content||Increase the drying temperature or time to ensure clear discharge hole.|
|The processing temperature is low, causing incomplete plasticization of the materials.||Improves the processing temperature reasonably.|
|The water temperature is so low that materials shrinks, resulting in a shrinkage cavity.||Reduces the temperature of die-head and improves the temperature of cooling water reasonably.|
|Feeding speed and the rotary speed of the main extruder are not matching.||Reduces the feeding speed or improves the rotating speed of the main machine properly.|
|The temperature in natural exhaust port is low, resulting in poor plasticizing. Under compression of the extruder, the material will leak.||Improve the temperature in the natural exhaust port to boost plasticizing.|
|The screw is not matched with the natural exhaust port in the feeding barrel.||Choose matching screw and feeding barrel.|
|No reverse conveying element or reverse kneading block is equipped in the port.||Equip a reverse conveying element or reverse kneading block.|
