Types and reasons for cartridge defective

Cartridge cost only takes a small part in the whole cost of a cannabis oil brand customer, but the cartridge is very critical for users to consume CBD or THC oil.

Many customers had headaches finding a satisfied cartridge supplier. Local distributors and big Chinese factories are expensive, Chinese small factory is much cheaper, but finding good quality and reliable one is not easy. A reliable small cartridge factory supplier becomes an advantage in the current competition.

Most quality problems happen during testing, try order and first order. Here are the common quality problems and the reasons that lead to them.

Problem: Leakage
Reason: Sealing, hole size choosing, and filling method.

Problem: No-work
Reason: Short-circuit or open circuit.

Problem: Burning taste
Reason: The balance between burning speed and oil soaking speed.

Problem: Break & fell apart
Reason: Material quality and dimensional tolerance.

Problem: Clog
Reason: Hole size choosing and oil soaking.

There are other defective problems such as bubbles, oil inhales to mouth, oil change color. All these problems are related to hole size choosing, structure, material, process, and QC. A good defective rate is under 0.3% according to our experience.

Most hemp extractors, cannabis vape brands owner are familiar with the production process of concentrations, distillates, live resins, shatters, but have no idea how to find a good cartridge. Ask for a whole bunch of different cartridge samples from different factories and testing, waste a lot of money yet still didn't find a proper option.

Our factory has solved the problems mentioned above, welcome to contact us if you still have any problems in finding a good cartridge.


Honest leads to long-term cooperation

Luck leads to short-term success, ability leads to medium-term success, morality leads to long-term success.

As a factory that willing to root in this industry we care about long-term business much more than profit. The profit of one order means little for us, but stable orders mean a lot at keeping the workers, maintaining our priority at suppliers, sharing the fixed cost of factory such as rent/labor cost.

We aim at supplying brand customers with high-quality cartridges and build a long-term relationship, thus, the first we care about is quality. All of our customers find us because they meet the serious quality problem and suffered a huge loss.

I still remember the face when they talking this to me, the oil value more than 10 times of the cartridges, let alone their customers and brand reputation. I know if we can't supply a nice solution they will be customers of someone else and get a new customer takes more than 10 times effort to maintain an old one.

We'd like to build trust by quality, delivery time, price, service with you by time. Please stop cooperating with us if you realize we lie to you. In the end, honest leads to long-term cooperation.
