    • Structure: Reusable and Detachable steel cylinder molds design.
    • Features: The steel cylinder test mold is a mold made of steel plate that is highly wear-resistant, non-deformable, non-deforming, non-cracking, and easy to disassemble. It is mainly used for pressure testing and quality control in concrete structures. Due to its high strength and high density properties, steel test molds and forms are often used in construction where high strength or high density concrete is required.
    • Application: highways, railways, tunnels, water conservancy, schools and other concrete testing projects, learning courses, etc.
Types of steel concrete cylinder test molds According to different needs, steel trial molds can be divided into the following types: 1. Clamp plate steel trial mold: reusable and easy to disassemble. 2. Spring-type steel test form: This type of steel test form is easy to install and can be applied to various complex structures of concrete structures. 3. Lock-type steel test form: This type of steel test form is suitable for concrete structures that require higher density. Application scope of steel cylinder molds Steel test forms are mainly used for compression testing and quality control of concrete. In actual construction, steel trial forms are usually used in the following concrete structures: 1. Bridges: Bridges are one of the main application areas of steel formwork. Since the bridge needs to withstand high pressure and load, the steel test mold has sufficient strength and compactness to ensure the quality of the concrete. 2. Tunnel: Tunnel is another area where steel formwork is commonly used. To ensure the integrity and safety of the tunnel structure, the concrete must be sufficiently dense and strong, and steel test forms can provide these properties. 3. Reinforced concrete slabs: Steel test forms can also play an important role in the construction of reinforced concrete slabs. It ensures the compactness and high strength of concrete. When using steel test molds, you need to pay attention to the following matters 1. Correctly select the type and specifications of steel cylinder molds to meet the needs of the concrete structure. 2. Relevant regulations need to be strictly followed during the installation process to ensure construction quality. 3. The service life of the steel cylinder mold should be reasonably controlled to avoid damage or deformation. 4. The storage and maintenance of steel cylinder test molds should be highly valued to ensure their long-term stable use.

Base on injection process, we focus on plastic ABS molds & plastic Polypropelene molds more than 15 years. CATALOG OF CONCRETE MOLDS: Commercial concrete planter molds, Roman column molds, Breeze block molds, Baluster molds, DIY walk maker forms and other Garden decor molds etc.

Silicone molds for concrete have always been in a very high position among DIY enthusiasts. Inexpensive, easy to make, are its main advantages. Such as: Small planter molds, Candle molds, Soap molds, Skull molds etc.

Normally, The latex molds only for custom service, because it is the most cost-effective manufacturing process for customizing a small order of molds. Of course, silicone molds can also do this, The choice of latex or silicone ultimately depends on the customization needs of customers. The most common is to use in the production of concrete / plaster sculptures.

In the true sense, the size of industrial-grade concrete molds is very large, which has a great test for the durability of mold materials. Therefore, steel and fiberglass are the best choices. The disadvantage is that they can only be applied to engineering projects with relatively simple shapes. Such as utility poles, sewer wells, prefabrication of culverts, etc. At present, LCMOLDS accepted customized services only.



Prefabricated raw materials (concrete, silica gel, plaster, etc.), molds, release agent(for Plastic Molds only),gloves, goggles, scales, mixing tools, support, operating instructions, etc.

These will be better to help you complete the project.

Usually we often talk that the mold release agent is mainly used in plastic(ABS, PP) molds. Before pouring, it should be applied on the inner wall of the mold first. The advantage is that it is convenient to demould after the prefabrication is completed.

Molds made of other materials, such as silicone molds, are not suitable.

Concrete needs to be mixed, so you must control the ratio of various raw materials. During the pouring process, the construction should be done slowly and at a constant speed. When necessary, a vibrating table or a vibrating rod is required to remove the air bubbles in the concrete. After completion, wait for the concrete to solidify and form, depending on the temperature or environment, ordinary concrete takes 4-12 hours.

For the demoulding of large-sized concrete blocks, you can use a rubber hammer to lightly hit all angles of the mold, and the finished product will fall off naturally-provided that the mold release agent has been applied to the inner wall of the mould.

After the finished concrete is demoulded, its strength is not fully hardened, so it must be placed in a ventilated place to dry naturally (it takes about 12-24 hours). Note: Prohibit sun exposure and rain.
