The bottle blowing industry is also called the extrusion blowing molding industry or the hollow blowing molding industry. Customers in this industry use EBM or injection-stretch-blowing machines (also called ISBM) to produce plastic rigid packaging such as containers for cleaning supplies, cosmetic bottles, jerry cans, medical bottles, buckets, chemical barrels, etc. Gravimetric Batch Blender is an integral part of the industry
In bottle blowing production, most customers use virgin material, crushed material, additives and color masterbatch, and these materials need to be dose and mixed based on certain proportions, and the mixing accuracy requirements are also very high.
By traditional manual mixing, most customers use vertical color mixer or a large vertical blender, but there are many disadvantages by using these two types of mixing equipment, such as:
1. The error of manual batching is relatively large.
2. The formula cannot be kept confidential and is completely exposed to employees;
3. The ingredients process is cumbersome and the cycle is long, resulting in low production capacity;
4. The workshop is messy and affects the corporate image;
However, using gravimetric batch blender or called weighing scale can perfectly solve the above problems. Its main advantages are:
1. The batching accuracy is high, around ±0.5%；
2. Keep the formula confidential；
3. The batching process is fully automated, with fast speed and high production capacity, and avoids raw material contamination caused by human contact.
4. The workshop is neat and clean to enhance the corporate image.
5. The RS485 interface equipped with the weighing scale can be connected with the MES system or ERP system of the customer’s factory to achieve data sharing and provide reliable data support for the digital management of the enterprise.
Our company’s 2-in-1 machine creatively combines the gravimetric blender and the vacuum loader into one unit. It is compact in size, greatly reduces the floor area, saves space, and uses stainless steel pipes as air pipe to make the negative pressure air transport is smoother and the machine looks more beautiful.
This gravimetric blending system is widely used in the bottle blowing industry and some plastic injection moulding industries, and has been highly recognized and praised by customers. If you are also interested in this automatic mixer, please feel free to contact us.
