Strict Quality Control

December 11, 2019


In2015, R.S.L. joint with the Guangdong Rubber Association and the Guangdong Rubber Industry Research Institute to establish long-term cooperative relations,together set up a modern professional physics laboratory.

Our equipment is supplied and assembled by D&G, a well-known manufacturer of testing instruments in China.

This is a numerical control management physics testing laboratory, based on the modern CNC management concept, accurate and accurate test record the results of various experiments, and ensure that RSL can provide high quality and efficient products.

Major equipment

Bench hardness tester

For vulcanized rubber and plastic products, shao hardness tester is installed in the bench hardness tester,
the measurement is convenient and accurate, and also the rubber hardness, in rubber production site hardness testing, meet the standard.

Thickness gauge

This product can be used to detect the thickness of any material, and it is in the measurement of thickness at the same time to the sample surface a certain pressure, which can effectively avoid the compressibility or surface smoothness is bad because the sample has caused by the data of the volatile situation.
It is mainly used in film, paper, sheet material (such as PET, PVC), aluminum foil, copper foil thickness test, in addition, it can be used in battery separator, copper chip and textile test in batteries.

Optical magnifier

1) Flat field, multiplier standard
2) The image is high and clear, without distortion and aberration
3)Both sides adopt import vacuum coating protection, super lens transmittance, can effectively prevent lens damage and mildew
4)Equipped with 6400K ring without shadow or white light or with uv fluorescent lamp, the light can be irradiated from all angles

MDR-2000 non-rotor-free vulcanizator(MDR-2000)

The mdr-2000 non-rotor-free vulcanizator is a company that compares the advantages and disadvantages of various vulcanization, and combines self - innovation.
It can be used to determine the characteristics of rubber vulcanization, as the basis for the actual production in the factory, and also for basic research, the important equipment for the control of ingredients.

1)Real Windows 7 software full function control - international standard (test results can be stored for comparison, amplification, statistical analysis, color printing, and networking), and upgrade can be guaranteed.
2)Modular structure design (machine, electricity) - high reliability and convenient replacement of spare parts.
3)European production of main cylinder (CAMOZZI, Italy) - long life (and low pressure can be used)
4)High accuracy standard sensor (American brand) - high accuracy, no correction (no f-v deviation error, and resistance error can be self-tested and automatically corrected each time).

DXLL series computer type material testing machine(DXLL)

This is applicable and to seek the relationship between material and deformation experiment, for metal, non-metallic materials, mechanical parts and finished products on tensile, bending, stripping, compression, sag, adhesion, tearing and other experiments and analysis.

Main technical parameters:

1. Maximum load: 50000N
2. Load accuracy: + / -0.5% (> 2N)
3. Measuring deformation: 0-1200mm (0.02)
4. Effective test stroke: 1000
5. Measuring accuracy: + / -0.05mm (150mm international standard sample stick)
6. Speed accuracy: + / -0.5% FS (self-powered for all non-metallic standard, entire range)
7. Speed setting: automatic computer
8. Power protection mode: arbitrary setting of computer

Main features of equipment:

1. Measurement system:

1) the fully automatic measuring system, without grade, can guarantee the accuracy automatically, and can easily measure the accuracy of + / -0.2% of the display value, and the most powerful time is the fine resolution.
2) American brand full force sensor (with automatic set).
3) automatic standard force, standard long calibration system, can be carried out by any metrological department for dumpster calibration (add some standard force, enter password password, and the length calibration is the same).
4) automatic measuring system.

2. Mechanical structure:

1) adopt gantry frame structure, the gap of the high precision ball double wire rod load to ensure rigidity and load on the machine efficiency, and has a larger test space, used for all kinds of test, to guarantee the machine big load test function and easy operation.
2) bearing (Japan), synchronous belt full import, many stainless steel components, (cover shell stainless steel).
3) low resistance of laser calibration (far less than other manufacturers) measurement and elongation system.
4) the encoder of the patent structure does not need to disassemble (the limit is the German position sensor) at the high and low temperature box.

3. Driving device:

The motor is the British dc servo torque motor (anti-overload).

4. Data system:

1) the Chinese Windows xp version of the software is free to upgrade at any time, and all curvilinear color inkjet printing (the most advanced software output color curve report)
2) test in the process of real-time dynamic display load, deformation and displacement, speed, maximum strength, breaking strength, elongation at break, tensile modulus and other test data (with many car plastic function) and stress - strain curve and the test results automatically save, read, analysis, amplification, calculation, judgement, statistics, etc.

Air aging test chamber

Air aging test chamber in hot air circulation way, prompting specimens aging, inner carton sealing strong, with ChouHuan air box inside the device, the overtemperature automatic cut off protection device, conform to the requirements of the ul - 1581 test.

Used to test wire, cable, insulator or coated rubber test film to compare the tensile strength and elongation of aging before and after aging.
