近年來(lái)，隨著我國(guó)城鎮(zhèn)化進(jìn)程的快速發(fā)展，復(fù)合井蓋的需求越來(lái)越大，無(wú)論是城市規(guī)劃，還是公路建設(shè)，都需要大量使用強(qiáng)度高、性能好的優(yōu)質(zhì)復(fù)合井蓋產(chǎn)品，所以，樹脂復(fù)合井蓋等復(fù)合材料復(fù)合井蓋逐漸取代了傳統(tǒng)的鑄鐵復(fù)合井蓋和水泥復(fù)合井蓋，成為復(fù)合井蓋產(chǎn)品的主流。

那么，作為專業(yè)的復(fù)合井蓋生產(chǎn)廠家，應(yīng)該怎樣選擇復(fù)合井蓋模具呢?選擇復(fù)合井蓋模具的關(guān)鍵是看模具的制造材質(zhì)，具體來(lái)說(shuō)，對(duì)于尺寸和形狀穩(wěn)定、產(chǎn)量較大的產(chǎn)品，應(yīng)該使用高性能的制造材料。而對(duì)于形狀多變、制作周期長(zhǎng)、要求精度較高的產(chǎn)品，因?yàn)槠淠＞叩募庸べM(fèi)大大高于模具的成本費(fèi)用，所以也應(yīng)該選用高強(qiáng)度的材料。對(duì)于形狀簡(jiǎn)單、承受應(yīng)力小、制造難度小的復(fù)合井蓋產(chǎn)品，就應(yīng)該采用改形的模具，這種模具通常使用鑄鐵、鋼或非金屬材料制造。

n recent years, with the rapid development of China's urbanization, growing demand for composite covers, whether it is urban planning, or road construction, require extensive use of high-strength, high-performance composite covers a good product, so resin composite composite manhole covers and other composite materials gradually replaced the traditional cast iron manhole covers and cement composite covers composite, composite covers mainstream products.

The key, then, as a professional manufacturer of composite covers, how to select composite covers mold it? Choice is to look at the composite covers mold mold manufacturing material, specifically, the size and shape stability, yield larger product, you should use a high manufacture of material properties. As for changing the shape of a long production cycle, requiring high precision products, because of its mold processing fee is much higher than the cost of the mold, so it should use high-strength materials. For simple shape to withstand stress, difficulty composite covers the manufacture of small products, should be used to change shape of the mold, this mold typically use cast iron, steel or non-metallic materials.
