Perfect quality system and professional quality team

Strict delivery inspection and gold medal after-sales service

Introduction To Our Quality Management

JM Precision has a professional quality team with sufficient quality personnel in all posts. Quality management personnel and quality engineers have more than 10 years of experience and specific excellent quality ability. All posts shall be trained according to the requirements, and take the post after passing the theoretical and practical assessment to ensure that the ability meets the requirements.

Quality Control Process

The quality part consists of three processes: incoming inspection, in-process inspection and warehousing & delivery inspection.

Incoming Inspection

In order to ensure that the raw materials meet the requirements, in addition to the routine inspection of material brand, heat treatment and standards, the hardness, chemical composition and mechanical properties of the raw materials will also be inspected or sent to a third party for testing.

Prevent fake and shoddy raw materials and standard parts, and conduct traceability inspection on material certificates or COC and physical objects based on lot number / batch number; Ensure the integrity of all chains of material manufacturers, distributors and agents.

In order to meet the environmental protection requirements, the supplier shall provide relevant COC certificates; Meanwhile, we regularly sends the third party for RoHS and reach tests.

In order to avoid mixing, color identification shall be carried out on the side of aluminum alloy raw materials in the warehouse to achieve visual management.

In-Process Inspection

CNC Machining Part

·In order to meet the measurement accuracy, three sets of Zeiss CMM are equipped with a minimum measurement accuracy of 0.001mm;

·In order to meet the measurement needs of large-size parts, 2 sets of Hexagon CMM are equipped ranging of 1200x900x800 mm.

·In order to meet the measurement needs of small-size parts, 8 sets of Rational Optical Imager are equipped. Measuring range: 300x200x150 mm.

·In order to improve the inspection efficiency, 2 sets of TESA Digital Altimeter are equipped with a measurement range of 0-700mm.

·In order to meet the inspection requirements of tooth holes, VTG brand and other brands of American and metric screw plug gauges, ring gauges and STI gauges are equipped.

·In order to meet the inspection requirements of fine holes, various pin gauges are equipped.

·There are also Mitutoyo Roughness Meter, caliper, micrometer, height gauge, dialgage and dial indicator.

Surface Finish Part
(Anodizing of aluminum alloy)

·In order to ensure the stability of aluminum alloy anodizing production process, it is necessary to test the current, voltage, pH value, conductivity, temperature, time, concentration and suspended impurities of each tank liquid.

·In order to ensure that the anodized oxide film of aluminum alloy meets the requirements, various performance tests need to be done, including Oxford film thickness test, Taber wear resistance test (hard anodizing), salt spray test, constant temperature and humidity test, color difference test, gloss test, color matching of standard light source, etc; All tests can meet ASTM B117 & ISO standards, or customized tests can be carried out according to customer standards.

Surface Finish Part
(painting & Powder Coating)

·In order to ensure the correct use of paint, it is necessary to manage the validity period of paint and powder; moreover, control the temperature and humidity of paint and powder warehouse is also needed.

·Kept 10,000 grade dust-free condition in painting workshop.

·In order to ensure the stability of the production process, the operation method of each coating shall be carried out according to the requirements of TDS documents, and the relevant parameters of each process shall be recorded in real time.

·In order to ensure that the sprayed film meets the requirements, relevant performance tests need to be done, such as film thickness test, hardness test (meeting ISO15184 & ASTM D 3363), adhesion test (meeting ISO2409), adhesion test (meeting ISO2431), impact test (meeting ISO6272-1), color difference test, gloss test and color matching of standard light source. All tests can meet ASTM B117 & ISO standards, or customized tests can be carried out according to customer standards.

Warehousing & Delivery Inspection

· In order to ensure the parts fully meet the requirements, a certain number of parts are sampled for 100% full dimensional inspection.

· For structural parts with special requirements, 100% material hardness and conductivity (MS / M) shall be tested.

· It is necessary to check the material certificate and surface treatment COC.
