1300-ton injection molding machine for one-time molding: How Lifangmei Technology's ABS antenna achieves hundreds of pieces without any flaws

The outer shell of an EAS antenna may seem simple, but achieving consistent dimensions for each batch and each unit is not something that all factories can do well. The ABS series antennas (AM8208, AM6208) from Lifangmei Technology are produced using a one-time molding process with a 1300-ton injection machine. Hundreds of pieces are continuously produced without any flaws, which is the quality foundation that enables them to supply in large quantities with stability.

Why is the accuracy of the housing important?

The EAS antennas are used in pairs. The two antennas on the left and right are installed on both sides of the entrance and exit, and they need to be precisely matched. If there is a deviation in the housing size, the position of the internal motherboard will shift, affecting the synchronization of signal transmission and reception. If the deviation is large, the detection distance will be shortened and the false alarm rate may increase.

The casing also needs to be sturdy enough. At the entrance of the supermarket, shopping carts often bump into the antenna. Poor injection molding quality leads to the casing cracking easily, or it may deform after long-term use.

What does a 1300-ton injection molding machine mean?

The tonnage of an injection molding machine represents the clamping force. The larger the tonnage, the larger the size and higher the density of the products that can be molded. The 1300-ton injection molding machine used by Lifangmei Technology can inject an adequate amount of ABS material at one time, filling all the corners of the mold.

The advantages are manifested in three aspects:

One-time molding: No need for secondary processing or repair, reducing dimensional errors

Uniform density: The material is fully filled, the shell has high strength and is not prone to cracking.

Smooth surface: No additional sanding is required after demolding, and the appearance is flat.

Developing molds independently to ensure consistency

The molds for the antennas were designed and developed independently by Lifangmei Technology, rather than being outsourced to a third party. This means:

The maintenance and improvement of the molds are under one's own control.

Each batch of production uses the same set of mold standards.

Why do customers care about this?

For overseas distributors, product consistency directly affects after-sales service. If the size of each batch of antennas deviates, there will be problems when installing them in the customer's store. Lifangmei Technology's ability to produce hundreds of pieces without flaws means that distributors can purchase in bulk without worrying about differences between batches.
