Common models and dimensional tolerances of Heat Insulation Strips

(1) The common models of Heat Insulation Strips are: type I, type C, and type T.

Other models such as Y-type and YF type are made according to customer requirements.

Note: type I, C and t Heat Insulation Stripss can be based on the section of the Heat Insulation Strips

Shape recognition.

(2) The width of the Heat Insulation Strips depends on the customer's needs, and common ones are


24.0mm, 28.0mm, etc

If the width is < =20mm, the allowable tolerance is ± 0.05mm; if the width is >20mm, the allowable tolerance is ± 0.1mm

(3) Thickness of Heat Insulation Strips > =1.8mm

If the width of the Heat Insulation Strips is > =20mm, the thickness of the Heat Insulation Strips is > =2mm, and the allowable tolerance is ± 0.05mm

(4) The angle of the Heat Insulation Strips is 4.2mm, and the allowable tolerance is ± 0.05mm. IV. characteristics and storage precautions of the Heat Insulation Strips

It is best to store the Heat Insulation Strips in a dry and ventilated environment at room temperature, because the characteristics of polyamide are that it will become soft and its size will become larger in a high temperature or humid environment, so that the Heat Insulation Strips cannot pass through the profile cavity; In low temperature environment, the Heat Insulation Strips will become brittle and smaller, and it is easy to crack when threading, which leads to

The profile is scrapped. In addition, the storage time of the thermal Heat Insulation Strips should not exceed one year. If the storage time is too long, the thermal Heat Insulation Strips will slowly absorb the moisture in the air, and the thermal Heat Insulation Strips will degrade and become very brittle, resulting in the non use of the thermal Heat Insulation Strips

Packaging of Heat Insulation Strips 


There are two kinds of Heat Insulation Strips packaging, one is straight strip packaging, the other is roll strip packaging.

Straight strip packaging:

(1) 100 pieces / bag

(2) 50 pieces / bag

(3) Each 6.02M

Roll packing: it depends on the model, specification and delivery quantity

Heat Heat Insulation Strips product label

1. Name, address and contact information of the manufacturer

2. Trademark

3. Product name

4. Quantity, length and specification of each piece

5. Production date, inspection batch number and inspector code

Heat insulating strip laser coding

Marks shall be printed on the side of the Heat Insulation Strips. The mark shall appear at least once every 500mm. Mark: Specification and model, national standard number and manufacturer.

Quotation of Heat Insulation Strips

The thermal Heat Insulation Strips are quoted by meter, and the ton price is taken as the calculation basis and assessment basis. Due to different shapes and weights per meter, the difficulty of production is also different.

I-shaped strips are converted according to the ton price and the weight of different grams. The pricing method of special-shaped Heat Insulation Stripss (C, t, y, etc.) is: ton price * difficulty coefficient = ton price of special-shaped strips (special shaped bar ton price /1000000) × MEG weight = price per meter of special-shaped strips (the difficulty coefficient of C and t types is tentatively set at 1.05, and other special-shaped strips are to be determined)

For example, if a special-shaped strip weighs 120g in grams and the difficulty coefficient is 1.2, and the ton price of the I-shaped strip is 50000 yuan / ton, the ton price of the special-shaped strip is 50000*1.2=60000 yuan / ton, which is converted into the price per meter (60000/1000000) × 120 = 7.2 yuan / meter

Heat Insulation Strips mold

In addition to the existing mold specifications and models on the company's mold list, if there is a new mold, the mold drawing must be sent back to the company first, and the order can be received only after the company's technology department determines that the mold can be opened. The review cycle of the mold drawing is 1-2 months, and the mold opening cycle depends on the difficulty. The cost of new mold opening varies according to the degree of difficulty, and the mold opening cost is $8000-12000. If there is a special mold (it is very difficult to open the mold), the mold opening fee will be negotiated separately.

Insulated strip container

1 container volume

Internal volume of 20 foot container: 5.69 m * 2.13 m * 2.18 m, maximum cargo weight 17.5 tons

Internal volume of 40 foot container: 11.8 m * 2.13 m * 2.18 M. the upper limit cargo weight is 22 tons

2 packing scheme

20 foot container:

(1) The length is 5.69m, and the straight bar cannot be installed

(2) Take c-28.0 as an example:

500 meters per roll

Weight per meter gram: 90.4g

Outer diameter 1m

Thickness 0.15m

There are 2 rolls in each row, 5 rows, and 14 high rolls in each row, totaling 140 rolls.

Installable weight =140 × five hundred × 0.0000904 tons =6.328 tons

40 foot container

(1) Straight strips can be installed at the front of the container for 6.1 meters, and coiled strips can be installed at the back of the container for 5.7 meters

(2) Take c-28.0 as an example: straight bar:

50 pieces per piece

Volume: 0.048m ³

If the allowance of 0.5m height left on the top of the container is not included in the volume, 400 straight bars can be installed (447 in theory)

Straight bar weight =400 × fifty × six × 0.0000904 tons

=10.848 tons

Roll strip:

The coil can hold 6.328 tons with the same weight as the 20 foot container

Total installable weight =17.176 tons
