HLJH - a professional manufacturer and supplier of cutting oil in Taiwan.


Q & A

When we use the industrial oil, we always are facing to....

The cutting oil is mainly due to maintenance machine that can operate smoothly but also produce an unpleasant smell, the foaming in sink, the effect of lubrication and rust, etc.
How can we solve that?

There are few reasons cause foam that resulted in exposure to the air during processing.First, there is not enough space for sink. Second, the machine accolated too much iron filings, it caused liquidity is not well.At first, you can add defoamer to improve the foaming problem, but it isn't a great method for long time. It depends on situation, one of the method that choose the suitable cutting oil. Read More
Stinky problems always bother to operators that we can check few points. First, concentration it doesn't suit too high or too law. Second, it need to regular replacement of oil. Third, it depends on serious odor, can add HLJH's regulator. Finally, if above methods already tried then doesn't improve, you should change the sink of cutting oil.HLJH, can help you to take 250c.c to laboratory testing, confirm remedy for that oil. Read More
There are some suggestions that you can wear gloves or put lotion on your hands that in order to protect the skin; avoid to touch the oil directly. If only a few person allergy that could behalf of the personal problems. It also probably causes respiratory diseases (including asthma, pneumonia, etc.), allergic skin diseases and malignancies, we can use the eco-friendly cutting oil, it's a security method.HLJH, use the natural vegetal mild formula is harmless to human, can be called " environmental cutting oil ".

Ask or check that oil whether have the certification of RoHs and TRGS.If lubricant's viscosity is too high, it may not flow adequately to where it is needed; if lubricant's viscosity is too low, the fluid might not sufficiently separate and protect the parts as intended the best way to select and maintain proper lubricant viscosity in a system.Take these two steps: 1. Consult lubrication experts to select the proper product for your specific component, application and operating conditions. 2. Use the machine for analysis the viscosity of lubrication, such as Four Ball wear testing. Read More
High precision cutting oil: There is a great lubricant effect and anti-rust; processing temperature is higher that easy to produce the mist of oil then make dirty work environment.Water Soluble Cutting Fluid: There is a great cooling effect that long-term u sage lower than costs.On the other hand, cutting different types of fluid per oil products has a different chemical composition, if mixed them will cause the other chemical changes easily. We need to understand that condition which give the best suggestions or can refer to our application of cutting oil. Read More
Waste of cutting oil contains many chemical ingredients, if it is emissions at random not only violating of law but also cause serious pollution of environment even effect healthy.It's need to handle by the industry that having qualified certificate for wastewater treatment.HLJH set up class B treatment plant that can help to handle the industrial wastewater treatment; provide the wastewater treatment machine that converting waste into water.According to different areas, there are different rules that can refer to the EPA Executive of regulations. https://oaout.epa.gov.tw/law/LawCategoryMain.aspx?CategoryID=11 Read More
What are these certifications?RoHS - RESTRICTION OF HAZARDOUS SUBSTANCES RoHS stands for Restriction of Hazardous Substances, and impacts the entire electronics industry and many electrical products as well. The original RoHS, also known as Directive 2002/95/EC, originated in the European Union in 2002 and restricts the use of six hazardous materials found in electrical and electronic products. All applicable products in the EU market since July 1, 2006 must pass RoHS compliance.TDS - TECHNICAL DATA SHEET A Technical Data Sheet is a document from a supplier, which describes the technical data of a raw material. The TDS shall normally been approved before any tests of the material ,and contain any information that is important for our use of the material in the intended application.REACH Reach stands for Registration, Evaluation, Authorisation and Restriction of Chemicals,is a regulation of the European Union, adopted to improve the protection of human health and the environment from the risks that can be posed by chemicals, while enhancing the competitiveness of the EU chemicals industry. It also promotes alternative methods for the hazard assessment of substances in order to reduce the number of tests on animals. In principle, REACH applies to all chemical substances; not only those used in industrial processes but also in our day-to-day lives, for example in cleaning products, paints as well as in articles such as clothes, furniture and electrical appliances. Therefore, the regulation has an impact on most companies across the EU.If the risks cannot be managed, authorities can restrict the use of substances in different ways. In the long run, the most hazardous substances should be substituted with less dangerous ones.SGS SGS is a multinational company headquartered in Geneva, Switzerland which provides inspection, verification, testing and certification services. The core services offered by SGS include the inspection and verification of the quantity, weight and quality of traded goods, the testing of product quality and performance against various health, safety and regulatory standards, and to make sure that products, systems or services meet the requirements of standards set by governments, standardization bodies or by SGS customers.SDS - SAFETY DATA SHEET A safety data sheet (SDS),is a document that lists information relating to occupational safety and health for the use of various substances and products. SDSs are a widely used system for cataloging information on chemicals, chemical compounds, and chemical mixtures. SDS information may include instructions for the safe use and potential hazards associated with a particular material or product, along with spill-handling procedures. SDS formats can vary from source to source within a country depending on national requirements.A SDS for a substance is not primarily intended for use by the general consumer, focusing instead on the hazards of working with the material in an occupational setting. There is also a duty to properly label substances on the basis of physico-chemical, health or environmental risk. Labels can include hazard symbols such as the European Union standard symbols. The same product (e.g. paints sold under identical brand names by the same company) can have different formulations in different countries. The formulation and hazard of a product using a generic name may vary between manufacturers in the same country.COO - CERTIFICATE OF ORIGIN A Certificate of Origin (CoO) is a document that evidences that the goods in your export shipment were produced, manufactured, or processed in a particular country. It requires standard information, like the exporter, consignee, shipment routing, and goods description. It also includes two additional sections specific to the document: Exporter Declaration – A declaration by the exporter to the inspector vouching for product details and the country of manufacture. Inspection Certificate – A certificate completed by a state employee or an outsourced agency signifying that the goods were inspected.COA - CERTIFICATE OF ANALYSIS A Certificate of Analysis is a document issued by Quality Assurance that confirms that a regulated product meets its product specification. They commonly contain the actual results obtained from testing performed as part of quality control of an individual batch of a product. Read More
