1. The company's time in business

Although a company's operating time does not fully represent its strength, a large part represents its familiarity with the field, the longer they do the more familiar with the field, and solving your problems will be.

For example, like RINA TECH, our company has been operating for eleven years and our sales manager (Judy Liu) has more than ten years of experience in this field, handling many optical cases, solving problems and difficulties for many customers and providing optical solutions for them quickly.

2. Reputation and customer service policy

A company that has been operating in a field for a very long time must have accumulated certain customer reviews, and if a company doesn't even have any customer feedback, it is important to consider its professionalism and competence.

Customer service policy is a very important point, it means that your supplier can give you what kind of service as well as protection, RINA TECH from the beginning in order to service, will arrange professional sales staff for you, starting from the design of professional optical solutions or maintenance program for you, and for your program signed a confidentiality agreement, and a set of mature inspection standards, packaging, and transportation are according to the highest standards to The final after-sales issue is also guaranteed by a special agreement. From the moment you ask us, we will always be there for you.

3. Product maturity

Product familiarity is the most critical point to determine whether a supplier is professional, because I ultimately around the product, to our light guide plate, for example, a professional supplier must know how much the thickness of the conventional light guide plate, what thickness is suitable for what kind of optical scheme, and light guide plate has several different materials, different materials on the working environment has what kind of requirements, etc. If you want to know whether your supplier is professional, you can ask her for more product knowledge, if not even familiar with the product, then you have to consider whether she is professional.

4. Sample Quality

If you can't tell whether your light guide supplier is professional or not after doing the above, then you can take a sample order from your supplier, and take a sample for testing, the sample is the most effective way to test whether the supplier is professional and reliable, because there is no way to lie about the product, if the sample quality is not good, then the supplier's professionalism and integrity is also worth considering.

How to test the quality of the light guide plate？

1. Packaging: Checking whether the packaging is intact, the packaging is intact is a step to check the quality of the product, and packaging quality to ensure the safety of the product.

2. Check if the material is correct： First you have to check if the material is the one you want， PMMA, PS, or MS laminate? PMMA is the best, MS is medium, and MS is the worst. 

3. Check its appearance for problems： The main problems included in the appearance are surface soiling, damage, bad dots, burrs, black and white dots, black and white lines, or dark spots, all of which can be judged by visual inspection. 

4. Check product performance： This needs to light up the light guide to check its brightness as well as light and dark, and needs to have lighting equipment.
