1,pre-sale support:
Normally we suggest you paint our standard color , but we can supply customization paint service by paid.
2,after-sale service:
Warranty:1 year for machinery,6 months for electrical.
For mechanical parts, our guarantee duration is 12 months. If the part is broken within this period, we will send the spare parts immediately to the client for repairing.
3,technical support:
Normally, we send our engineer(s) to supervise the installation and commissioning. The buyer need to prepare the operation staff to implement it. BORETECH is able to send mechanical engineer, electrical engineer and operation engineer. The operation engineer is to help the buyer's labors to know how to operate the washing line and get the best efficiency.
Boretech is one of the major supplier of PET bottle recycling system in Asia . We uses the around 30 years of fiber making and bottle recycling experiences to manufacture PET Bottle recycling machine and configure Pelletizing line, Polyester Staple Fiber line, POY line and Bottle to Bottle Line. At present, we have supplied about 170 sets plant for more than 30 countries.Our customers in the US, Japan, EU manufacture food grade rPET resin for such well-known brand owner's such as Coca Cola, Niagara Bottling, Nestle, etc.
Boretech can help our customers to make right configuration of the machinery, and find the right position in the industries. The most important value is that we can help our customers to minimize the learning cost and to avoid making any mistake during investment.
