Product Features

1. The Chipboard Screw is also called Screw for Particleboard or Screw MDF. It’s designed with a countersunk head ( usually a double countersunk head), a slim shank with an extremely coarse thread, and a self-tapping point.

2. The countersunk/ double countersunk head: The flat-head makes the chipboard screw stay level with the material. In particular, the double countersunk head is designed for increased head strength.

3. The thin shaft: The thin shaft helps to prevent the material from splitting.

4. The coarse thread: compared with other kinds of screws, the thread of the screw MDF is coarser and sharper, which digs deeper and more tightly into the soft material such as particleboard, MDF board, etc. In other words, this helps more part of the material to be embedded in the thread, creating an extremely firm grip.

Production Technology

Chipboard Screw:

1. Heat treatment: It is a method of heating steel to different temperatures and then using different cooling methods to achieve different purposes of changing the properties of steel. The commonly used heat treatments are: quenching, annealing, and tempering. What kind of effects will these three methods produce?

2. Quenching: A heat treatment method in which the steel is heated to above 942 degrees Celsius to make the steel crystals in austenitic state, and then immersed in cold water or cooling oil to quench to make the steel crystals in a martensitic state. This method can increase the strength and hardness of the steel. There is a very big difference in the strength and hardness of the steel with the same label after quenching and without quenching.

3. Annealing: A heat treatment method in which the steel is also heated to an austenitic state and then naturally cooled in air. This method can reduce the strength and hardness of the steel, improve its flexibility, and facilitate processing. Generally, steel will go through this step before processing.

4. Tempering: Whether it is quenched, annealed or press-formed, steel will generate internal stress, and the imbalance of internal stress will affect the structure and mechanical properties of the steel from the inside, so a tempering process is required. The material is kept warm continuously at a temperature of more than 700 degrees, its internal stress is changed and then cooled naturally.

Factory Introduction and Advantages

In 2008, Tianjin Xinruifeng Technology Co., Ltd. was established in the beautiful coastal city of Tianjin. After more than a decade’s development, now we are a leading, professional and premium manufacturer with excellent capabilities of design, development, production and export. Our main products include drywall screws, chipboard screws, self-drilling screws and self-tapping screws, which are produced in 3 different production bases with a total area of 16,000 square meters.

We have 280 sets of automatic production equipments, including wire drawing machines, cold-heading machines, thread rolling machines, tailing machines and heat-treatment lines. There are more than 100 staff in our company. Among them, there is an experienced and professional R&D team, who follow an established management system and quality control procedure, allowing us to customize the products according to your specific designs/requirements to the highest quality. Further, we have CE Certification for drywall screws and SGS will conduct audit to our factory on a regular basis. Because of this and our great attention to high quality, there is not a single complaint about quality in the last 5 years.

Research and Development Capabilities

1. To satisfy the demands from markets and customers, we have more than 300 machines in two shift production in order to provide all kinds of fasteners in the market home and abroad.

2. To prevent any mistakes from happening during the developement, the development procedure is strictly controlled under ISO 9001. From design → information collection → setting developing items → design input → design output → pilot run → design verification → mass production, every stage is strictly inspected & controlled by our R&D team. Based on the precise control from research, drawing, pilot run management and design change, the development will be cost effective and efficient.

Application

The chipboard screws are mainly used for woodworking such as furniture assembly or flooring, etc. This is why we also call it screws for particle board or screws MDF. We offer a wide range of chipboard screws whose length is from 12mm to 200mm. Generally, the small chipboard screws are perfect for fastening hinges on chipboard cabinets while larger screws are used to join the bigger pieces of a cabinet, etc.

Basically, there are two kinds of chipboard screws: white zinc plated or yellow zinc plated. The zinc plating isn’t only a layer of protection to resist corrosion, but also matches the aesthetic of the project. Besides our chipboard screw is characterized by a deeper Pozi recess that helps to avoid cam-out and also extends the life of the bit used to drive the screw.
