High-performance rubber recess formers: high-quality materials, precision manufacturing and strict quality control

Rubber Recess Former is a key auxiliary tool for precast concrete components. It is mainly used to form standardized grooves for installing lifting systems (such as lifting anchors) or other fasteners. In construction, infrastructure construction, rail transit, energy, and other industries, rubber recess formers are widely used due to their high precision, durability, and ease of use.

This article will comprehensively analyze the definition, materials, manufacturing process, application scenarios, installation steps, maintenance, and industry selection standards of rubber recess formers to help construction units, engineering contractors and purchasers better understand its functions and advantages.

What is a rubber recess former?

The role of rubber recess former

The main function of the rubber recess former is to form standardized grooves on the surface of concrete components to ensure that the lifting device can be installed smoothly. These grooves are usually used for:

·Connecting the lifting clutch (Lifting Anchor) to achieve safe and efficient lifting operations.

·Fix the anchor system to improve the bearing capacity of the concrete structure.

·Reserve space for pipelines or fixings to ensure accurate installation of equipment.

Main application scenarios

rubber recess formers play an important role in multiple industries, and common applications include:

·Construction industry: Standardized lifting points for prefabricated beams, plates, columns, and other components.

·Infrastructure: Lifting operations of concrete components such as bridges, subways, and highways.

·Power and energy: Lifting needs of transmission tower bases and wind power foundations.

·Port terminals: Used for the installation of large concrete pile foundations, offshore platforms, and other components.

·Rail transportation: Lifting solutions for prefabricated components of subways and high-speed railway bridges.

Materials and manufacturing processes of rubber recess formers

Selection of rubber materials

rubber recess formers generally use special rubber materials that are resistant to high temperatures, oil, and corrosion to ensure their stability in different construction environments. Common rubber materials include:

·Natural rubber (NR): has good elasticity and wear resistance, suitable for general construction environments.

·Synthetic rubber (SBR): has better oil resistance and anti-aging ability, suitable for long-term repeated use.

·Silicone Rubber: Excellent high-temperature resistance, suitable for extreme climate conditions.

·Polyurethane Rubber (PU): Stronger wear resistance, especially suitable for high-intensity construction scenes with frequent use.

Manufacturing process

rubber recess formers are usually produced by compression molding or injection molding:

Compression molding: The rubber raw material is heated to a certain temperature and placed in the mold, and high-pressure molding is used to ensure the product size is accurate and the surface is smooth.

Injection molding: The rubber is injected into the mold by high pressure, and then molded after high-temperature vulcanization, which improves production efficiency and enhances product durability.

Technical characteristics of rubber recess formers

High-temperature resistance

rubber recess formers can usually withstand construction temperatures of 80℃ to 120℃, while formers made of high-performance materials such as silicone rubber can withstand environments up to 250℃, making them suitable for high-temperature maintenance environments.

Oil resistance and corrosion resistance

During the construction process, the rubber recess former may come into contact with release agents, lubricants, chemical solvents, and other substances. The selection of high-performance rubber materials makes the former have excellent oil resistance and is not easy to age or deform, thus extending its service life.

Reuse

Compared with disposable plastic or metal formers, rubber recess formers can be reused many times and can be restored to use with simple cleaning, effectively reducing construction costs.

Accurately match lifting clutches of different sizes

Lifting Clutches with different load requirements requires grooves of different sizes. HULK Metal can provide customized rubber recess formers to ensure perfect matching of customer needs and improve construction accuracy.

Installation process of rubber recess former

Preliminary preparation

Ensure that the construction template is clean and free of dust and oil.

Ensure that the former is not damaged and check whether the rubber has cracks or aging.

Installation steps

Fix the former: Install the rubber recess former to the specified position of the concrete template. It can be fixed by magnetic fixers or mechanical clamps.

Pour concrete: Pour concrete according to construction standards to ensure that there are no bubbles or inclusions around the former to prevent affecting subsequent installation.

Wait for the concrete to solidify: usually 24-48 hours, depending on the ambient temperature and concrete mix.

Demoulding and removing the former: After the concrete has completely hardened, carefully remove the formwork and remove the rubber recess former to avoid damaging the groove shape.

Subsequent inspection: Make sure that the groove size and position meet the design requirements, and clean the former for next use.

Common problems and solutions

The former is not installed firmly, how to deal with it?

·Solution: Use a high-magnetic fixture or mechanical clamp to ensure that the former does not shift during the pouring process.

Are there bubbles or unevenness on the edge of the groove?

·Solution: When vibrating concrete, ensure that the vibration is uniform and use a high-flow concrete mix.

If the former is damaged or deformed, can it continue to be used?

·Solution: Check whether it is caused by overuse or improper storage. If obvious cracks or deformation are found, replace it with a new one to ensure construction quality.
