Black profile extrusion method:

在型材配方中到场色母料，颠末挤出机间接挤出黑色型材，长处是在原挤出机上挤出制品，资本较低；错误谬误是型材的耐候性差，很难知足室内的装璜功效的请求。

Participating in the color masterbatch in the profile formula and directly extruding the black profile through the extruder has the advantage of extruding the finished product on the original extruder with low cost; The disadvantage is that the weatherability of the profile is poor, and it is difficult to meet the application of interior decoration results.

覆膜法：

Film coating method:

操纵加热和机器覆膜的方式，颠末压合将一层黑色膜和粘结胶粘结在绿化护栏的外表。出产制作进程中须要在流水线前程中，品德较好的膜和粘结胶选用入口制作品，资本较高；施工时黑色膜碰伤时不好修补。

A layer of black film and adhesive are bonded to the surface of the green guardrail by pressing the method of heating and mechanical film covering. In the process of production and manufacturing, it is necessary to select imported products for high-quality film and adhesive in the future of the assembly line, with high cost; It is difficult to repair the black film when it is bruised during construction.

外表喷涂法：

Surface spraying method:

精选色的涂料平均的喷涂在绿化护栏的能够瞥见的外表上，能够单面的喷涂，也能够双面的喷涂，色采多样，出产制作矫捷便利。

The paint of selected colors is evenly sprayed on the visible surface of the green guardrail, which can be sprayed on one side or both sides, with various colors and flexible and convenient production.

复合共挤法：

Composite co-extrusion method:

首要是由绿化护栏和一层附加的黑色物料配合挤出组成的型材，出产制作型材利用一种复合模具，出产制作的唱工是昔日两个分歧六道的型材物料和黑色物料，在分开模具之前汇流到配合挤出成型。

The profile is mainly composed of green guardrails and an additional layer of black materials, which are extruded together. The profile is produced using a composite mold. The singing skill of the production and manufacturing is that two consistent six-channel profile materials and black materials flow into the common extrusion before leaving the mold.
