Excellent upgrade for our old machinery
We converted two of our coarse spinning machines using this kit. The precision of the fine spinning output is remarkable, and the downtime was minimal. Highly recommended for factories looking to modernize without buying new units.

Good value but requires skilled installation
The conversion kit works as advertised and improved our yarn quality significantly. However, you definitely need experienced technicians for the installation. The support team from Qingdao Shangjiayi was helpful throughout the process.

Cost-effective solution
Instead of purchasing brand new fine spinning machines, we opted for this retrofit. It saved us nearly 60% of the cost while delivering comparable performance. The build quality of the replacement parts is solid.

Solid performance increase
The transition from coarse to fine spinning was seamless after the retrofit. We noticed a slight learning curve for the operators, but the final product quality makes it worth the effort. Delivery was on time.

Smooth operation post-conversion
Our production line has been running smoother since the conversion. The noise levels are lower, and the fiber handling is much gentler. Great product for extending the life of legacy equipment.

Professional manufacturer support
Qingdao Shangjiayi provided excellent documentation and remote guidance during our installation. The machine now produces fine yarn with consistent thickness. A very reliable upgrade path.
Q: Can this conversion kit be installed on carding machines older than 15 years?
A: Yes, in most cases. Our engineers can assess your specific machine model to determine compatibility. Please contact our support team with your machine's serial number for a detailed evaluation.
Q: How long does the typical installation process take?
A: For a standard single-machine conversion, the process usually takes between 3 to 5 days, depending on the condition of the existing frame and the availability of your technical staff.
Q: What is the expected increase in production efficiency after converting to fine spinning?
A: While results vary by material and original machine condition, most clients report a 20-30% increase in value-added output due to the ability to produce higher-grade yarn, along with reduced waste.
Q: Is training provided for operators after the conversion?
A: Yes, we offer comprehensive on-site or virtual training sessions for your operators and maintenance staff to ensure they understand the new fine spinning settings and safety protocols.
Q: Does the retrofit include a warranty for the entire machine or just the new parts?
A: The warranty covers all new components supplied in the conversion kit and the labor performed by our certified technicians for 24 months. The original frame and non-replaced parts remain under their existing status.
