Makers of window & cabinet locks emphasize customization

Companies are increasing the diversity of their selections to attract more buyers.

China suppliers of window and cabinet locks are updating their product range to meet the requirements of different markets. Although the main structure and function of the fittings remain the same, minor adjustments in shape, size and style are carried out to deliver models for specific segments.


Window lock
Shaoxing Thcoo’s model A710 window lock comes in zinc alloy.

In cabinet locks, manufacturers are coming up with designs that can be adopted in various enclosures, including those for telecom, electronics and electrical equipment. Depending on the target application, models are configured to be mounted onto square, round or oval-shaped holes.

For windows, the selection is expanding to cover units for different openings.

Structural modifications are focused on the closing mechanism.

The latest releases include pieces with a device that needs to be pushed up or down, or left or right to secure the window to the frame. There are also models that need to be rotated clockwise or counterclockwise.

To suit target applications better, aesthetic changes continue to be implemented in the two categories.

Qingdao Luqi Lock Fty Co. Ltd, for example, offers stainless steel locks with a polished or sanded finish in bright white for window frames in the same material and aluminum versions.

For office cabinets, Shaoxing Thcoo Locks Manufacturer Co. Ltd's selection comprises zinc alloy models featuring a pure black coat.

Under efforts to diversify their product range further, several suppliers are rolling out variants that last longer or provide better security.

Make Locks Manufacturer Co. Ltd is among the companies that have taken this step. By adopting virgin zinc alloy and a steel cam, and employing one-time punch molding instead of die casting, it has extended the service life of its models to 150,000 turns. This is in contrast to mainstream designs that can withstand only 100,000 cycles.

A number of enterprises, including Make and Shaoxing Thcoo, are also improving durability via surface treatment. Several releases for the high end can now withstand salt mist tests for 56 and even 72 hours compared with 48 hours previously.

As regards security upgrades, suppliers are increasing the number of key codes to prevent one key from opening similar locks.

Make, for instance, has developed a cabinet lock that has more than 10,000 key codes, as opposed to the standard 5,000 for other versions in the market.

Some enterprises are taking security a notch higher by adopting better materials for the inner components. Zinc alloy with a higher hardness rating and stainless steel are among the inputs being adopted for this purpose.

Other manufacturers, including Yuhuan Wasble Machinery Co. Ltd, aregoing beyond adjustments of the physical structure to enhance protection against unauthorized access and are incorporating electronic systems in their designs.

Products & prices

For cabinet locks, cam and pin tumbler types are the common options offered. Versions priced at less than $5 are usually made of zinc alloy. These have undergone 48 to 56-hour salt-mist tests and have a service life of about than 100,000 turns.

With regard to security, most cam locks in this segment have fewer than 10,000 key codes. Series for pin tumbler types do not exceed 1,000.

For models that are priced a minimum of $5, zinc alloy and stainless steel are the raw material options. Many meet RoHS requirements.

Designs have typically gone through a salt-mist test lasting 72 hours and can be used for more than 100,000 opening-and-closing cycles. Cam and pin tumbler locks have over 10,000 and 1,000 key codes, respectively.

For windows, latch and sash locks are the common options. Prices start below $1.

Similar to cabinet locks, models are typically made of die-cast zinc alloy. In the upscale segment, some are in stainless steel.

Prices are about 10 percent higher than levels in early 2010, due primarily to the increase in raw material and labor costs. The former rose 20 to 30 percent, while wages went up 10 to 20 percent last year.

In coming months, suppliers are not expecting any significant leaps in raw materials and labor costs. A continued appreciation of the yuan against the US dollar, however, is anticipated to push quotes upward.
