JCL Machinery

Since the late 1960s, JCL had been building machines such as press machines and feeder for the glass industry. Due to increasing project requirements since 2000, JCL began to joint-venture with its partners in China to produce a wide range of machineries for the glass industry, including press machines, annealing lehr, blowers etc. Other than offering customers with a lower cost option for machines, JCL has been continuously working on the improvements of its machine products, through technical tie-up with European and Japanese manufacturers. JCL is active in listening to customers' feedback and as such is able to introduce many improvements to its machines.

Annealing/Decorating Lehr

Our annealing and decorating lehrs are suitable for the heat treatment of glass containers and tableware after forming. The purpose of the annealing lehr is to relieve the stress in the glass containers after forming. The purpose of the decorating lehr is to allow chemical bonding of the print onto the glass containers, after printing.

​

In order to achieve temperature homogeneity in the lehrs, they are designed with the following specifications:

• Fans: All heating and cooling zones are equipped with air circulating fans.

• Burners: Venturi-type On/Offf burners are used to ensure even heating and temperature control.

• Inner Wall: Heat resistant stainless steel (AISI 409L or AISI 304) is used for all inner walls of each zone.

• Belt Material: 1Cr13 or AISI 304 stainless steel

• Thermocouple: Stainless Steel Sheathed Ni Cr type K thermocouple is installed in each zone

• All the temperature control meters on the control panel are imported from Japan, model TM225 and Belt speed is controlled by invertor from Fuji, Japan. 

Tempering Lehr

Our tempering lehrs are used for the heat treatment of glass tableware in order to increase their mechanical resistance towards impact and thermal resistance from high temperature change. This helps to prevent cracking or shattering of glass tableware if they are dropped onto the ground, or from shattering if they are put in high temperature, e.g. microwave oven  

Belt-Type Tempering Lehr

Our Belt-Type tempering lehr is suitable for the tempering of glass plate and bowl. The design of
preheating zone and heating zone are similar to that of annealing lehr with circulating fan. After the heating zone, all the glass articles require immediate and even cooling-down in order to toughen the glass plate. The cooling ducts with adjustable pressure cooling air are provided. Each cooling duct is connected through air pipes to a rectangle box which has many small air tubes. The rectangle air tubes are positioned above and below the glass article in order to cool down both sides of the glass article evenly.

Spindle-Type Tempering Lehr

Our Spindle-Type tempering lehr is suitable for the tempering of glass tumbler
and bowl. This lehr consists of 3 zones as follow:
1. Preheating Zone. With 4m conveyor and 5 sets of burner firing, where the rotating glassware are preheated to high temperature.
2. Heating Zone. Through 15m heating tunnel constructed with refractory and 16 burners, the glassware is heated up to about 680°C evenly.

3. Tempering Zone. 5 Sets of high pressure air cooling chamber are designed to quench the
glassware from the top, bottom and both sides evenly.

​

​

Mould Pre-heating Oven

The Mould Pre-heating Oven is used for heating up the moulds before they can be put onto the machine for glass production. Moulds can be pre-heated by natural gas firing or by electrical-heating.
