Development Centre
R&D System
We are investing 15% of our annual sales into our R&D lab., developing for instrument and technical updating, that's a commitment most other makers can't match. All this research has paid off. Meanwhile, our professional design makes company getting a name and many profits. We are currently carrying out reliability tests on new products.

Creation is H&L’s soul by a marketing product developing system with powerful engineer team and management combining with professional laboratory and development center.

EMI Testing
We have a very skilled quality control team to solve problems and provide customer service. We have our own laboratory facilities to carry-out reliability testing and have passed ISO17025 approvals. We also employ team of safety testers to assure our products conform with safety standards.
Incoming material must be inspected by IQC. In process, every line has one IPQC to make production inspections, including first product inspection. We perform final inspection according to FQC. On outgoing products, we perform inspection according to OQC.
